I'm Restoring my 78 and thank god I have access to a very large cabinet blaster. My question is can I sand blast aluminum? Specifically the intake manifold? If i do, can I paint it? Should I paint it? What do ya think
He is correct , glass bead is the media you should use. Much less aggressive than sand or silicon carbide media. You could have that done for under $20 at most blast shops.ken_79-fj40 said:Be careful on the mating surface to the head. Personally I would put some fine glass bead media in there for the stuff you don't want all pitted. I used my friends glass bead blaster for lots of stuff, didn't pit it nearly as bad as my sandblaster. My heater box, for example I bead blasted, primed, painted and then installed. Looks perfect.
