Just one last bit of evidence as to why I prefer butyl tape for deck hardware over Devil's Glue or its extended family of misfit relatives.
EDIT - 2/19/2013: These genoa tracks are still bone dry having not yet been re-bedded since this boat left the factory in 1979!
This is the genoa track on our CS-36T as photographed at year 31. The track is still bedded with the original butyl tape she left the factory with in 1979. The track 31 years later was still BONE DRY, does not leak and has not leaked, ever, in 31 years and 50,000+ nautical miles. We run a 150 genoa most of the year, just as the previous owner did, so this track sees some heavy loads.
I've seen some 4 year old boats bedded with Devils Glue or its relatives dripping wet with rust stained bolts and wet core at year four and sometimes earlier.
Oh and this genoa track was installed without countersinking the holes. Just an aluminum genoa track bedded with butyl tape in 1979. Bevel the holes and it will probably go 70 years without a leak.. (wink)
