I have used both Rustoleum and Krylon. I do not like Krylon nearly as much as Rustoleum. Also, I much prefer to paint a bike with a paint brush. Spraying a bike frame is difficult because over spray is usually a problem (over spray occurs when you paint one stay, for example, and the over spray hits the other stay). Also, I can paint a bike, with a brush, in the kitchen with no fear of getting paint everywhere.
