Fiberglass and Titebond 3


Hi Shorty,
Attached are to progress pics. One is a close up of how I sealed the outside edges. I used tightbond 3 glue overtop fiba tape. It makes a really strong hard waterproof seal.

My question is regarding the inside. I was thinking of using a latex caulk sealer on the inside seams and painting everything with a primer and latex paint. I bought Dap Dynaflex Ultra. I got mine at Lowe’s for about $9. It is a paintable latex caulk that claims to be weatherproof. It is not approved for marine use but It has a 50 year durability guarantee. That is what the company said when I emailed them.

Do you know of anyone that has had any success using it?

Thanks,
Joe

Me personally, I have always used painters caulk on the inside edges of everything that is joined together. It is the cheapest tube of caulk I can find at Home Depot, like $2 per tube.

The reason I do it is trying to keep the water out of the joint. But... over time from flexing and weathering, there always opens up a small crack and I wonder if I am actually just creating a cavity to keep water inside the joint and encourage rot? If I didn't use any caulk, would that let water in the joint drain and dry out faster? I dunno.

This would be a good topic to discuss and hear from other duckers and what type of results they have experienced.
