My Corrosion-X stopped ?weeping? after a couple of years. Must have something to do with the fact that here in West Texas when we have summer we really have summer. I am guessing that due to the high temperatures the light ends cook off and the ?weeping? ends. It just takes longer for you guys in cooler climes.
This March I pulled one of the wing skins over the fuel tank bay (a fairly easy job now that I have SS screws) just to check on the corrosion situation. Just a described everything was coated with a gooey mass, but no corrosion (big surprise ? not).
I plan to check every couple of years and when the goop isn?t sticky any longer give it another dose of Corrosion-X. Is Corrosion-X be all to end all? I really don?t know. But after my very unhappy experience with corrosion a few years back I just don?t want to take a chance.
