Thru bolt hull to top - advice wanted

[stoney]

I am curious about why you want to glass the cap to the hull. Is there signs of the deck cap being loose?
I just recored the deck cap last year my 1971 23 SF. The boat had been used and abused for 34 years and the screw together method showed no sign of loosening up. It made it very easy to remove the deck cap. If you ever have to take the deck cap off again it would be brutal if it is glassed on. The deck cap has to come off to redo the transom and we seem to like to do that job. I used the installation procedure that came with the Taco rub rail and the only problem is with screws pulling through the rail. Might be the particular rub rail I bought. Back up the screws with #8 SS flat washers so they can't pull through the rubrail. The rub rail job is a 3 man project. Good luck
