I was reading the latest issue of Hemmings Muscle Machines and the article about wet sanding your finish caught my attention. My GTX has some light sanding marks under the paint. I never thought I could get them out without re spraying the car, which is not an option anytime soon. Anyway, if anybody read the article, or has some advice about wet sanding, compounding etc...I would appreciate it. I have a daily driver that is perfect for me to practice on. It's a 1990 Capice that has original paint on it. The car's been outside everyday for 20 years so the finish is basically flat white. I'd feel better if I practiced on the Caprice before doing anything to the GTX. Thanks.
