Terry Farrell asked: "Heat activated? What exactly are you describing here. Most any epoxy will cure more quickly when heated and most any epoxy will decrease in viscosity when heated. Are you describing something beyond that? I use West System epoxy. I don't know exactly how the two viscosities compare. West System is about the same viscosity as most pancake syrups. I have used it on bridge pins with great success." My reply: The Epotek 301 (lately sold by Ruth McCall) was a 24 hour cure, which means another trip but noooo problem with working time. It is also about "syrup" thick but under a gentle heat gun, it becomes very thin, like water, and man does it flow into all the little cracks and crevices. On bridges, if you fill the gaps then drive in a new, longer pin, it really forces a complete fill of all the damage. Then, there is no globbing of goo on the bridge at all---very little to scrape or sand off and no interference with a good string seating. I think it's great but Ruth has gone out of business, retired actually. And I would like another source for this product which, incidentally, was developed for electronic components and wiring in satellites. Alan Barnard Salem, MO
