So, I've never owned a Saturn before in my life, and thus have never washed and/or waxed a plastic-bodied car before. And I am a FREAK for keeping my car clean, from the first day it's 50 degrees I'll wash my car once or twice a week & wax it once a month or so. HOWEVER, I don't know if the procedure is any different for a plastic car. Can you use the same wash & wax? I figured it's all the same PAINT so it wouldn't matter, but I don't want to screw up the car. Anybody?
