[pianotech] Applying PVC-E to new plastic keytops

[David Stocker]

PVC-E has some gap filling capacity, but the straighter the surface, the 
better. Much depends on how you surface the key. I find if I actively press 
down on the entire length of the top, I have few problems. I may have a 
couple with some air gaps that can be fixed with some glue on a pallet 
knife.

I think like the idea of masking tape better than a spring clamp. I'm sure 
the spring clamp works better, but if I don't have to own another large 
uni-tasker tool, . . .

Glue sizing sounds interesting, if it increases PVC-E's effectiveness. Part 
of the appeal of PVC-E is that it never gets hard and can take the abuse of 
hard playing. Too thin would not be better. What made you think of glue 
sizing?
