What kind of rubbing compound. I bought Mothers last nite and they say that works great. But ive been rubbing it in for 2 hrs last nite and i gotta do more today. Alot of people dont know how to apperciate a classic and i have alot of hits on my car door. So since i have a show on sat i want to get her into shape or at least try to get out as many dings as i can. So wha should i use?
