Default Re: I found sand blasting aluminum prior to powder coating is a big no-no.

For smaller parts we usually use a vibratory tumbler, takes longer but it's less expensive than blasting.
The tumblers are a great idea, but I would need too many of them for it to be worth the investment. Right now, I simply de-burr with a 90* die grinder and sanding pad, hand wash in warm soap and water, spray down with acetone and shoot.

I have the system down, it requires very little prep and the pieces are turning out great. I find that the powder coat forgives "sins" that anno won't.
