This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi Carl. My info is that elevated curing temperatures can tend to weaken = the cured epoxy. It would concern me to heat bridge pins. It may not be = a valid concern as I'm sure the heat is dissipated rather quickly. I = have always found West System to be thin enough to wick into all = birdseye cracks around bridge pins - when the pin are removed. I'm sure = it would be nice to have an even thinner epoxy - although, I wonder if = it would be as convenient to apply - the thicker West System holds a = nice drop on a wire or on the bridge pin base for application! What is = the strength characteristics of the Epotec301? Is it as strong/hard as = West System resin? Do you have a web site for Epotec301? Oh, and BTW: Just sent out an old Fisher upright with a completely = rebuilt action and a VERY nicely leveled set of keys!

I'm waiting for a = spec sheet for clear coat, but I think it is similar to liquid wood. There may be other qualities of epoxy that will enhance penetration, = but I would think viscosity would be the primary one. Warming the pinblock, bridge or other items helps a great deal.
