I'll second Alex's comment about the old 3M Scotch-Weld being impossible to remove. My Series 5 came with a dented elevator push-pull tube, so I needed to fabricate a new one. I tried to remove the machined end fittings from the old tube to re-use, but even with a propane torch the Scotch-Weld would not release. I boogered the fittings up so badly in the attempt that I ended up ordering new ones from Kitfox.
