Hi! Everyone!! I just joined this forum today. As I'm reading about the roller painting skill, All I can say is WOW!!! so now I want to do that on my car too, but I have a few questions to ask:

1)If using a roller, isn't there will be rolling marks between each rolling area? How did you guys take care of that?

2)I noticed there should be at least 6 coats, so do I have to thinning the paint each time?

Thanks guys
