I use West System, = among other things, to secure bridge pins when repinning an old bridge. = After cleaning the bridge cap, sanding out the string grooves, and = renotching, I put a drop or two of epoxy into the bridge pin hole, dip = the tip of the new pin in epoxy and tap it in. As the excess oozes out, = I take a fine brush dipped in lacquer thinner and spread the excess = epoxy over the cap and into the notches to seal the wood. After it = cures I paint on a thin coat of permalon--I've gotten away from putting = graphite on the bridge. 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?

I have heard from others that a product called Epotec 301 (my spell = checker suggested "erotic", but I think it is Epotec) may be thinner = than West System resin. I have not tried it. I had the address, but I = cannot find it now. Anyone have the address? I'm sure Epotec makes a fine product. But it sure is hard getting = product information out of them. We have used WEST system epoxies since the early '70s with much = success. They make excellent products. But when it comes to coating = epoxies we use SystemThree (http://www.systemthree.com) Clear Coat = Epoxy.=20 To quote, "Clear Coat epoxy is a very low viscosity (thin) almost = colorless epoxy system that has a long pot life and cures without amine = blush. Unlike some of the so called penetrating epoxies, Clear Coat = contains no solvent. Furthermore, it is a very strong system when cured = whereas the penetrating epoxies have little, in any, strength or = resistance to moisture." This stuff really is nearly water thin. It also = requires an extended cure time--depending on the temperature from 36 to = 72 hours. Del ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
