Hey guys, I'm looking to spray paint an old South African FAL butt stock I'm working on refinishing. Truthfully, the whole rifle could use some Cerakote, but I don't have that in the budget at the moment. So, this is a stopgap measure. My guess is some of that heavy duty engine spray paint, but should I throw down primer first? Or, is it more a matter of "dammit, man, you're spray painting, who cares?"
