I have done numerous wetsands on stock paints in the past. On older cars it was much easier, but on some of the newer paints it is a lot tougher. Most newer paints have too much OP and way too many peaks and galleys and are very broad in measuerment. There has been a few people lately that want their new cars wetsanded and unfortunately there was too much difference within the peaks and galleys. It could be done on some of these newer cars, but I honestly wouldn't suggest it because of the lower quality of some of the newer paint systems. Nothing will happen during it, but in 3-5 years paint failure will speed up. A lot of the newer paints are not designed to be perfect but it can be done. Heck, a lot of them do not even like to be polished.
That's why I use so much IPA (alcohol), so I can get the car drunk and take advantage of it.:laugh:
If a customer doesn't mind spending a few thousand, and sign a long term contract, then I'll do it.
