Flash copper over pot metal
Anyone tried this? I have had mixed results. I'm trying to re-finish some old bathroom fixtures which are pot metal die-castings. I purchased some "cheap-o" faucet handles from the local hardware store which were also pot metal die-castings and plated them with Flash Copper, then with Acid Copper, then Copy Chrome, and they came out perfect!
These older parts however, are giving me fits.
If I try to degrease or rinse with ANYTHING, (even distilled water) it turns the parts dark, or dull. Should I just shine them up with sand paper and then go directly to the Flash Copper after a quick rinse with distilled water?
