Well, I just found out about a growing trend in DIY auto painting. You can thank the power of the Internet. Many bloggers and automotive journalists are raving about the results that are being achieved with Rust-oleum and mineral spirits mixed 1:1, a roller and lots of drying, sanding, painting, repeating as necessary. Some car guys are satisfied with the results of 5-7 coats, others go for as many as 10. It sounds like a lot of work. When you consider that a professional job costs about ten times as much, you can understand why people are doing it.
