How to repair damaged copper tub
1. Is it possible/practical to attempt powder coating in a home shop?
2. I mistakenly used a power circular steel wire brush to get out some stains on a copper tub. This has "discolored" the copper in places (I suspect bits of steel impregnated into the copper). I have tried to remove the discoloration with rubbing compound, buffing, etc, and then prepped again with a commercial alkaline solution, but the splotches are still there.
Any suggestions?Patrick Laughlin

I bet the tub is copper plated steel. Try a magnet on it, I bet it attracts. You've simply buffed through the copper.George Brackett III

Hi, Patrick. The principal advantage of powder coating is environmental: the plastic powder is melted onto the parts rather than requiring any solvents.
There are simple consumer style powder coating kits available.
