Thanks for the answers. So my idea to de-plate the pot metal handles using a #3 pickle (sulfuric) and reverse polarity is a bad one? I was al ready to go out and buy some acid, but it now just clicked that acid+pot metal=problems.

Can you tell me the best way to filter my Copy Chrome solution? Something in the manual about charcol filter? Where to get this kind of charcol? Is it the kind found in aquarium supply stores?

I did try the copy chrome system with s few pieces of copper pipe first, and had execellent results.

I ordered the pot metal primer and some brightener. What kind of blasting abrasive do you recommend for pot metal? Would aluminum oxide be too aggressive??

Thanks...
