Nanowax will just temporarily hide the scratch, not remove it.
Hi Guys,
I'm a Marketing Director for a bodyshop in Canada and I myself just purchased a 2007 IS250 AWD.
If the scratch has gone through the clear coat, then no matter what product you try using, you'll always see that scratch. The only way to get rid of it is to paint. Your car is black, so in order to do a Spot Paint Only is possible, and its the most economical way to repair such scratches. Spot Paint Only repairs do not require blending or painting of any adjacent panels, so beware of shops that try to charge you extra for this. They should be able to repaint just that spot and match it perfectly. An average Spot Paint Only repair will cost you from $80 to $150, depending on the shops hourly rate.
If the scratch is not under the clear coat, bring it to a professional detailer to buff it out. Do not, and I repeat, do not try to buff anything out yourself if you've never used a buffer before. I've had many customers come to our facility with damage that was caused by self buffing. You can easily go through the paint if you've never tried buffing before...which in the end will cost you even more to repair.
Some shops will charge you $50 to buff that area....some may even do it for free just to get you as a customer...I know I would.
I hope this helps.
