Durham's Rock Hard Soundboard Putty

[Farrell]

When I epoxy bridge cracks at the pins, I use just resin and hardener - no filler. If I were to fill a crack in a board, I would mix an appropriate filler in the epoxy. So the subject piano may have a right nice epoxy repair on the soundboard.

Del Fandrich wrote a very nice article on epoxying soundboard cracks. Don't know exactly where it is. Go to the West System web site - they have tons of info on using their products.
