Charlie Young is probably correct in his statement, "given the moderate cost of Weigle's Framesaver and the fact that it was expressly designed for the task it isn't worth using another formulation."
But, Walt's comment about LPS-3 is also not far off. I spent 2 years in the Marshall Islands (Kwajalein Atoll), where salt was a definite enemy of the equipment. Framesaver wasn't available, but we went thru tons of LPS-3 to protect the missile launchers and other exposed metal from the corrosive environment. It was and is cheap. And, a favorite hobby there was to watch your bike rust. If you got tired of that, you could watch your friend's bike rust. This was in 1980 and several of the more afluent residents were riding early Klein frames. They were considered beyond the means of most of us, but when equipped with stainless spokes and cables, we all lusted after them. Oh, and our version of the Iron Man Triathlon was the Rust Man. Great memories. Lou Deeter, Orlando FL
