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?
