jyardgirl, I have just started, I painted my trailer that I just finish building. Turn out ok, and I paint small car parts, I just want to say pay attention to the pros, you can rent a fresh air mask out from your local tool rental its very important. I don't no much about painting but plan on buying me a fresh air mask set, Hobby Air has one for around $500. Check this out hope link works.
