Re: Stus-List caulk question and West 6-10 to the rescue
my apologies for the newbi question, can the West 6-10 be used to fill areas where the wet balsa core is scrapped out. I'm rebedding some hardware and repairing a few soft spots.

Re: Stus-List caulk question and West 6-10 to the rescue
Joe It is a lot of effort but, you'd never have to worry about it leaking back into the deck. Just that fact that it is trough bolted moves the path of least resistance below the deck. I just did this process for 6 deck hatches! took me 5 boat weekends! now that I'm done, I'm happy I took the time and did it right. I'd hate to think I took a 36 year old dry deck and ruined because of careless hardware bedding... Also, don't for get to countersink the holes, even if you do just screwing it to the deck.

Re: Stus-List caulk question and West 6-10 to the rescue
Joe, I'm a fan of the 6-10 for overdrilling screw holes too! I've also used it for gluing wood mounting blocks to glass. You never know when someone is going to loose their balance and grab whatever they find. I'd want the added insurance of fasteners.

Stus-List caulk question and West 6-10 to the rescue
My old vent over the head finally UV rotted and fell apart. I bought a nice new Marinco stainless steel solar vent and got busy getting the old deck fitting off. First thing I discovered was the source of a longstanding leak that has been driving me nuts, the old vent was not well caulked and water was getting into the core on the outboard side and getting between the deck and the headliner, where it would migrate and leak :( First thing is a core repair RIGH NOW because it will rain tomorrow, so I scooped out the rotten balsa and used a hair dryer to dry out the remaining core. I went to West to get some Marine-Tex to fil in the gap and I already have epoxy for sealing the wood. I was looking around and spotted West System 6-10 in a caulking type tube that you use with a caulk gun. It comes with a mixing nozzle too. I cannot overstate how impressed I am with the 6-10. It is SO easy to work with :) The nozzle allowed me to inject the mixture into the core and totally fill the gap I scooped out. The mix is think enough to stay in the gap and liquid enough to attach to the good core. I was going to run home for my MAAS epoxy to finish the job, but I used my finger in a glove and was able to seal the core with it too. All was well until I had nose itch and got epoxy on my nose and my glasses LOL. Questions - the new vent does not fit into a deck plate, it is designed to mount directly to the deck. They suggest using silicone caulk. I already have 4200, would that work? Also I my experience, something with that much flat surface against the deck is going to be very well glued on by the caulk.
