Thanks folks! It's slow work but I am pleased with what is showing so far. Dan I ordered one of those small Euro brushes. That might work well on some of the tough spots. Chief, all I used was the hairspray to seal it. It's water soluble so it comes off easy. In the cleaning process, just using water, no chemicals. When I am done, I think I will use a light coat of 50/50 white glue and water mix. Iron Patch and others have recommended that for pewter buttons. It dries clear.
