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.
