Removal of Textured Powder Coating from Bathroom Fixtures
I need to remove a textured, powder coat from brass plumbing fixtures, leaving a smooth substrate as well as unharmed threads for a untextured/smooth powder coat application It was suggested these pieces could be dipped in a acid bath, but wonder if this will affect/pit the substrate metal as well as affect the threads. I have heard about soda blasting, but don't know if this is effective on textured surfaces. These pieces CANNOT be replaced.Rudolph Gall
You can have the powder coat chemically stripped without pitting the substrate. You just have to be sure that you are not working with a stripper that is too aggressive.Adam Adkisson
You can also sand these smooth by hand, it doesn't sound like the volume warrants doing anything too extravagant, and then powder coat over the smooth, freshly sanded surface(try not to sand it to bare metal if possible). Powder is a good primer for powder, it might be the quickest, easiest way.
