A Lexus is "just a car" - Not to many of us! Pride of ownership is one thing that drew me to this forum to begin with. Researching and finding out how to make our baby look her best and to protect the finish is well worth the effort.
As far as product recommendations, I asked if anyone had tried OptiSeal in a previous post on this thread, and now have some feedback to pass along. I tried the OS on our daily commuter (94 Accord), to check it out first, and the results were fantastic. Repeating what others have already said, the preparation steps are the most important part, so having seen the difference that claying and polishing did for our 12 year old Honda, I am definitely a believer. After the Honda, I did our 07 IS250 AWD (Smoky Granite Mica).
The OS goes on super easy - you spray the clear OS onto a yellow foam applicator that comes with the product, then wipe it on in slightly overlapping swathes. There is virtually no pressure required and unlike wax where you rub it in, you simply are pulling the applicator across the paint. Its hard to tell that anything is going on, but if you look at just the right angle to the light you can see a slight film that flashes off pretty fast. It takes about 15 minutes to do an entire car, and if you do it correctly, that's it!! That is why they call it a WOWA product (Wipe On Walk Away)! I re-loaded the applicator a little more frequently than required and had a couple of minor streaks. All these streaks required were a gentle wipe with a MF towel and the finish looked perfect. As I stood back I thought, "this looks really nice", but I was hard pressed to say it looked better that a good wax job (it just took less time). Then, a couple of days later, I was in the garage getting ready to head out to work. After turning on the lights I was amazed to see the finish was just "glowing". The shine was somehow deeper and wetter looking - the term liquid comes to mind. It is really hard to describe, and the picture I took just does not do her justice! Based on these results I plan to use OS from now on. BTW - I am not a professional detailer, having just purchased our Lexus in August, and I just started researching and reading about detailing at that time. I don't have a PC and do everything by hand, so even beginners can get fantastic results!
Hey tex2670, Optiseal is so easy to use, even you might have enough to time to make your Lexus more than "just a car"!
