Well that will work and should last a long time. I usually just use a good quality rattle can. I guess the base clear is the same as what is one the body of the truck?
The paint on the body is old, thin red paint that I'm giving a "worn patina" look. I've never done it before so my expectations are low, but I actually like how it's coming out so far. The paint is so thin that I'm removing areas with acetone and a scrub pad, which is kinda cool since it doesn't leave sanding marks. I'll post some photos..
