Hey guys,
I've got a cheap, cast aluminum air cleaner lid. I soda blasted most of the painty off (then rinsed it), then used some paint remover to get the remainder of paint off.
I only used metal wash to clean it and didn't heat it to out gas(I know that now). It came out TERRIBLE!!
I've heard of soaking/boiling in a simple green/water mix solution, using some obscure prepping juice, and just sand/water rinse and go.
So, what are the PROPER procedures to prep a (cheap) piece of cast aluminum for powder coating?
Also, how do I fill scratches in the metal?
I can post pics if needed.
