Any wooden boat
shipwrights or marine service
techs lurking with lots of experience bedding hardware
Im re-bedding my aluminum
sheet tracks, they are screwed down and through bolted through a 2 inch thick teak
caprail and the bolts run right through the fiberglass
bulwarks to the inside of the boat
My question is regarding what sealant
should be used between an aluminum
track and an oily hardwood such as teak. I have had opinions flung around suggesting it doesnít matter, just use sikaflex or equivalent, as well as people saying to use a polysulfide such as lifecaulk. So I found most the stores have the mahogany life caulk but it recommends you prime the wood
with lifecaulk primer first, of course none of the chandleries have this primer, just the sealant
In my personal experience bonding woods like ipe and lignum vitae Iíve found with a good dose of acetone before glueing or epoxy
just about anything can be made to stick.
That being said, these are long sheet tracks with tons of fasteners and Iíd rather do it right and not have to rip it all up in 2 or 3 years.
Have at me with your opinions.
Can you use lifecaulk without the primer?
