What about when you have to paint the bulk of the car? Like the roof, pillars and rear 1/4's all at once cause they're all one piece? Doesn't the paint on the roof dry by the time you get done one side and then start on the other, or are you starting on the bottom of one side and working up across and down the other side of the car? Or does the light coats and sanding make it okay? I'm pretty much just wondering if you have any kind of a seam line on the top of the car. Lol, and I emailed a link to this thread to my brother, and he wants to do it to his rampage. It'd be a perfect candidate to try this out on, seeing as the roller job done by the previous owner is looking real bad these days.
