RE: carl goldberg epoxy
Well, jcpenny, you were right on. I found it and it has the Carl Goldberg logo on it just as big as life. I had not noticed that before. It is eight minute stuff, so it is kind of limited in its' application, but it works well in the proper places. There is no manufacturer's name or logo other than the Carl Goldberg logo, so it would be difficult to find a source for it once these are gone. The guy I bought the props from included four no name gas tanks and two packages of this epoxy with the order. I had no idea he was going to do that. I thought I had only bought the props. These two tubes have never been opened. They still have the metal seal at the top and are very pliable. They will probably still be good.
