Started a project rebuilding my suspension A arms and such. In preparation for powder coating I cleaned then sandblasted the parts then wiped down with acetone and baked the parts to release any absorbed oils at approx 425 for about an hour, then left them in the oven for a day after cooling. The parts came out with a mostly even coating that looks kinda bronze colored, a nice golden brown. I wasn’t expecting that. Acetone doesn’t clean it up, but sandblasting removes it very easily. I don’t think it’s rust.
so, could it be rust? or is that normal? do I need to re-blast everything or can I just P.C. primer and black over it?
I’d hate to do all this work just to have it all fail after it’s back together.
