RE: Done with GP epoxy!!!
I have some stuff Hobby Shack used to sell. This stuff was great. It has not discolored, still works and is some where around 10 years old. They had it on super sale so I bought 5 packs of the big bottles. I stopped getting the Tower or GP glues and epoxy after a few issues of the Ca going bad after 2 weeks.
Best and cheapest epoxy I have had was from a composite store. It was their brand and a full quart of resin and a 8 ounce bottle of catalyst cost just a little bit more then the 9 ounce bottle from the LHS.
Might look for a shop that sells fiber glass and carbon fiber. They usually sell the good epoxy and resins.
Buzz.
