Quoted from phil-lee:Naptha removes wax better than anything else.In order to get a clean,dry surface for possible touch-up painting use naptha.
Agreed.
In terms of using alcohol, in my experience it will absolutely strip pre-diamond/auto clear. In some cases (like when I'm prepping for touchups and auto clear) that is what I want. When I don't want to strip the clear I use naptha for light cleanup or novus 2 when I need something a little more aggressive.
