I am curious about the clear coat epoxy because = it seems that it might be a better seal for the wood. Will it serve the = same function as a filler for small cracks as the West System? David Love The SystemThree Clear Coat epoxy is about as good as 'regular' epoxy in = terms of crack filling. Because it is so thin it penetrates into the = wood surface considerably more than thicker epoxies. If you're trying to = fill small cracks around bridge pins you'll need to go back over them = frequently as it soaks in. The stuff has a really long working life if = you don't mix overly much so this isn't all that much a problem. We've been making laminated caps for most of our bridge work of late and = have been using the stuff to seal the notches where the end grain shows = up. Probably overkill, but it really does soak in a lot. Most of the time we still graphite bridges as a matter of customer = preference. On our own pianos we do not. I fail to see the point of it.
