Yea but my Green TRF gets perfect copper traces no pits, no joke. Green trf under pieces of steel after? Would it work? My old way was cheep nail polish a cheep artist brush and direct etch. Nail polish remover to remove nail polish after acid bath. That could be done cheep by just going to dollar store for supplies and no more pits for your art work on copper. Kevin
