I painted my brothers 55 Chevy in House of Color candy red and pearl with base, tint coat and clear.
He was all done with car stuff for a while and let it sit for a month before trying to sand and buff.
That stuff was like concrete, or harder..Luckiy the paint had a nice gloss so it only got a light sand and buff..
Hopefully my 68 roadrunner will get some paint soon !!
