Summer time is on us, and now is the time to start giving your Lexus some TLC. Nothing like a beautifully clean and shiny car on a summer day B)

To help LOC members get their car looking its best, I will post a series of articles on car care over the few months.

The first one is claying your car - hope you find it useful.

Clay is a surface preparation bar that smoothes the paint and exfoliates contaminants.

Every car finish shares a common enemy: pollution. It relentlessly pursues your car from the second it leaves the factory until your car meets its ultimate demise. It's in the air we breathe, it's on the roads we drive, and it attaches to your car's paint, where it bonds and begins a process of oxidation.

Surface contamination, as shown by this diagram, are difficult to clean or polish off, yet paint cleaning clay removes it with ease.

When contaminants get a solid grip on your car's paint, washing alone may not be enough to remove them. Pre-wax cleaners also may not be able to exfoliate large particles. In this case, you have two choices: use a polishing compound, which removes a lot of paint material, or use a clay bar. Clay isn't a polish or a compound, it is a surface preparation bar that smoothes the paint and exfoliates contaminants.

USES FOR CLAY

Clay is not a cure-all or a replacement for polishing. It's a tool for quickly and easily removing surface contamination.

One of the many reasons for using clay is the removal of brake dust. Brake dust contamination, which attaches to painted rear bumpers and adjoining surfaces, is a metallic surface contaminant that can be removed safely and effectively by using clay.

These are the two most common retail kits available. On the left is the Meguiar's Quik Clay kit, which includes a bottle of their popular Quik Detailer detailing spray and a fine grade clay. On the right is the Clay Magic Perfect Finish kit, which includes a soap-based lubricant and fine grade clay. These kits each retail for $9.95 (£5.47 @ 13/06/2004)

Clay is also very effective on paint over-spray. If the over-spray is particularly heavy, you may want to seek the assistance of a professional. Tree sap and tar specks can also be safely removed with a clay bar.

You can also started using clay on your windows (exterior) to remove heavy road film, bug deposits and water spots. It works very well, and seems to outperform even the best window cleaners.

EVALUATING YOUR PAINT FOR CLAY

How do you know if you need to use a clay bar? After thoroughly hand washing your car, feel the surface of your car's paint. Do you feel bumps and rough spots? These bumps are contaminants attacking the finish of your car. Removing these surface contaminants (road tar, acid rain spots, bug residue, paint over-spray, brake pad dust, hard water spots, etc.) will improve both the look and health of your car's paint. By the way, you can magnify your sense of touch by inserting your fingertips into a sandwich bag or a piece of cellophane.

No matter how well you hand-wash your car, many of the contaminants that have worked their way into your car's paint finish will remain. Have you ever looked at your foam wax applicator pad after applying a coat of wax? What do you think that black stuff is? It's dirt, and you're waxing over it, sealing it in.

CLAY SAFETY

Detailing clay isn't new. Paint and body shops have been using it for years to remove paint overspray. Clay is fairly new to the car detailing market, and is very new to the consumer on retail shelves. In the early days there was always a concern that paint damage might occur if improperly used.

New technology detailing clay bars are made of fine polishing particles in a soft, malleable "clay" medium that allows the bar to be formed and kneaded. Some clay makers add color to make the bar more attractive or to identify bars of differing strength (co****ness).

Many clay products claim to contain no abrasives. This is stretching the truth. The reason clay manufacturers claim their products don't contain an abrasive is because the general public thinks the word "abrasive" refers only to aggressive, paint removing materials. The fact is that the abrasives in most automotive clay products are so fine that you will not see any reduction in paint gloss. After several uses, paint luster may even improve.

USING CLAY

Using clay is very easy, but you must follow the instructions. Use clay incorrectly and you will create a mess or scuff the surface of your paint.

Before using detailing clay, you must thoroughly clean and dry your car to remove any loose dirt. Direct sunlight should not fall on your car's surface, and it's best if the work area is relatively cool to prevent rapid evaporation of the clay lubricant.

Here, Holly demonstrates how she rolls an ounce of detailing clay into a ball before flattening it into a wafer. Rolling the clay also softens it so it can be easily molded.

After rolling into a ball, Holly flattens the clay into a nice round wafer that will fit comfortably in her hand.

To use the clay bar, you spray a lubricant on a small area of your car and rub the clay back and forth with light to medium pressure. If the lubricant begins to dry, you'll need to spray more. Clay is fairly sticky and cannot be used dry. Try using clay dry and you'll make a big mess and scuff your paint.

After a few passes with the clay, rub your hand over the area you cleaned to check for areas missed. You should feel a distinct difference between the areas you have clayed and the areas you have not clayed. Keep rubbing until all contamination bumps are gone. Finally, wipe the clay residue off with a soft microfiber towel, and buff to a nice luster. Just like waxing, work in small areas.

When your clay is flattened into a nice wafer, you spray both the clay and the paint with clay lubricant and rub the surface lightly with the clay. Three or four passes over an area is normally enough to do the job.

clay7.jpg

An alternative to spray detailing lubricant is good old soapy water. Be sure to rinse your wash mitt thoroughly and use a fresh bucket of soapy water, not what's left over from washing.

Check the clay bar frequently for hard particles. When found, pick them off. Make it a habit to occasionally knead and reform the bar so that a fresh portion of the bar contacts your car's paint. If you drop your bar of clay on the ground, it's history. Toss it out. Don't take any chances, discard the clay bar if it becomes impregnated with grit. Read the manufacturers' directions for the number of uses of their clay bar. Do not overuse a clay bar.

When you're finished claying your car, you should wash it to remove the lubricant film, then go over it with a pre-wax cleaner to finish cleaning the paint. Finally, seal your freshly cleaned paint with your choice of wax or sealant.

After claying one or two body panels, your clay will begin to look dirty. Don't be alarmed, that's just the clay doing its job. Flip the clay over and use the other side. When both sides are dirty, remold the clay into a ball again and flatten to reveal a clean surface.

OTHER USES FOR CLAY

Clay isn't just for paint. You can use detailing clay on any smooth, hard surface, including glass and chrome. Do not use clay on clear plastic, such as headlight lenses.

When you can no longer remold clay to get a clean surface, retire it for use on your windows. The dirty clay will not harm glass, and it's amazing how much dirt film clay can remove from your exterior glass windows.

You can also use your old clay to clean wheels. Clay will safely remove stubborn, embedded brake dust, tar and road film from all factory wheels. Clay is not recommended on wheels that do not have a factory clearcoat or powder coat finish.

With just a little effort, stubborn brake dust that even the strongest cleaners won't remove comes off with detailing clay.

CLAY FAQS

Here are some common questions and answers:

Q1. I dropped my clay on the ground. Can I still use it?

A1. The safe answer is no. Clay will pick up small particles of grit from the ground that will scratch your paint.

Q2. If I use clay do I still need to polish my paint?

A3. Yes. Clay will not remove swirl marks, scratches or etching from acid rain or hard water spots. Paint polish is still required to remove these paint defects. If your paint is new or like-new, detailing clay will significantly reduce the amount of polishing required to keep your paint in good condition.

Q3. What is the best clay?

A3. What label do you like? There are only a couple manufactures of clay, and the technology is protected by U.S. patents. Clay is manufactured with different levels of abrasiveness and colors to suite different applications. There are some subtle difference in technology (plastic vs. elastic material) and the firmness of the material. In general, softer clays are safer and easier to use. A firm clay cleans better with a little more risk of scuffing or scratching.

Q4. Is it better to use soapy water or a spray lubricant?

A4. Both work equally well. If you want to do the job fast, use a bucket of soapy water. If you want to work inside or do a thorough job, use a spray lubricant. With a spray lubricant you can wipe down each panel as you go and feel for areas you missed.

Q5. How do I store my clay?

A5. If your clay did not come with a re-usable plastic container, store it in a plastic Ziploc bag.

Q6. Will clay remove my wax?

A6. In most cases, clay will "scrub off" wax protection. Some paint sealants are hard enough to withstand being cleaned with clay, but most are not.

Q7. Is it safe to clay using my buffer?

A7. Detailing clay was not designed for machine application. Even so, there are a couple foam buffing pads designed to hold a waffer of clay. These systems work with the Porter Cable 7424 dual-action system. The risk of paint damage is too high to be worth any potential time saving benefit.

SUMMARY

Automotive paint cleaning clay offers many advantages in the removal of surface contamination from paint. Even in the hands of a first-time user, clay is safe and easy to use. Sure, if you use a dirty clay bar, scratches can result. However, compared to machine buffing, compounding, or using harsh chemicals, clay is safer, faster and easier.

I used the clay bar about 3 weeks ago. WOW, what a differance in the feel of the paint. I thought that I had a fairly clean car until I put my hand in side a plastic bag and felt the nasty grit! It all came off with the clay bar. Next is my wifes mini-van, should take me all day on that one. But it will be worth the results. :cheers:

Thank you for all the good info on "claying!"

I clayed my 1990 LS 400 and my next-door neighbor who sold me the car said it looked almost as good as it ever had (and he bought it new!).

It was very easy to do. Took me about four hours (including several breaks).

The clay cost about $23 (can use it multiple times) and the lubricant (half-gallon?) cost about $13. Versus ~$125 at a detailer.

I havent used clay on the Lexus yet,but having used clay for years in the past on boats and planes found your information to be right on the money so to speak. Very good information. I agree even if you just do it once a year to remove the debris of winter and wear and tear of contaminants.No one will be disappointed in the results or in the time well spent on their investments. Great information :D

Great article on clay. I have used clay for years and will make one suggestion to add to your information. Claying and using the spray just takes to long. After the car is spottlessly clean from a dedicated washing, rinse out your wash bucket and mix up a new batch with plenty of car wash soap. Get yourself one of those fuzzy mitts and hold the clay in it. Keep the area flooded with the soapy solution. This will allow you to clay an entire car in a half hour to an hour. The biggest concerns with working with clay are; 1. dropping the clay. IF this happens, throw it away. and 2. letting the area you are working become dry as it can cause the clay to stick. After a quick wash off and dry, I go over all the paint with Maquire's #1 Paint Cleaner if the paint appears somewhat compromised, or #2 Polish if the paint looks good. The add a few coats of Collinite #845 Insulator Wax and you are good for a long time. With regular washing and a quick detail with Maquire's Detailing Spray and a microfiber towel, your car will look good for over a year. I add additional coats of wax every 3 to 6 months. I have 5 cars and don't have to time to deal with waxes that prematurely wear off.

Maybe it's my Mothers yellow clay bar but I have never seen mine look dirty like that. There is definetly stuff on it but not like that. Maybe it is just the yellow. I am in need of a new one.

I tried to use clay to get off a sap spot. Mistake! That $hit is hard to get it.

Anyway, I love clay bar and recommend it to anyone who has never done it before. I like to use distilled water when I do my cars because I tend to spay a lot. Just me though.

Good point about the soap and clay. I hate when I hit a dry spot and feel it streak off the paint. Cringeeeee. Love, love, love paint cleaner though. I used it on my 7 last weekend that had not been cleaned in a couple weeks >0. Washed, clayed a bit then did the paint cleaner and then a coat od Megs tech wax. I love how that stuff smells. I am in need of a good polish though. I have not used one before. Any rec's?

Those tutorials are from the Autopia detailing community, we've partnered with them on this sort of thing over the years. Holly is the girlfriend of DavidB, Autopia's owner. I believe they broke up some years ago...

Yeah, but is she still doing Tutorials?

How about one showing what to do when the hose gets away from you while washing the car and gets you all wet, and you're wearing a thin white belly shirt and.....

Nevermind.
