[pianotech] Plate finish problems

[Dale Erwin]

Thanks Ron/Terry/ Al/ Greg and all who responded with suggestions.
  Ron...To be clear I wasn't about to leave any of the old finish on.  Ever things gotta go before the primer/magic wand/ filler/whatever is employed.  I wonder if the original japanning process is difficult or that specialized that it couldn't be replicated for plate jobs.
  Just think blast the crap off every plate and then pour on the japanning and start over. 
  Something else to add to my wish list along with a keyboard pounder.

This was the worst. The topcoat was really hard, flaked off in some spots, hung on like warts in others. I bought a needle scaler from Harbor Freight and hammered the whole mess off. Roughly the equivalent of blasting, but more work. <G> Evercoat Featherfill primer, sand forever, and topcoat as usual. A true pain.

I think you should stick with the blasting, rather than have the pour-on magic elixir stick in some places, and not in others. I'd hate to have to do one of these twice. Or if you feel lucky, maybe a marine epoxy primer, and metal flake gel coat it. I Have ideas, just not necessarily good ones.
