How do I seal the seams on a custom boat cover?
I'm currently making a boat cover for my sailboat. I'm using canvas because I have the material readily available to me. I'm concerned that my seams may leak. I plan on coating the cover with waterproofing spray to help shed water and leaves. The seams will be under stress and I'm looking for something other than the waterproofing in a can in which to seal the joined pieces and still afford protection from leaks. If anyone has any ideas it would be greatly appreciated.
Triple stitched, flat felled seams in canvas should not leak without any sealant. I have a cover from the below link for last NINE years in year-round sun & it is still in good condition. Cover was 6 or so years old at least when I got it but was winter stored under cover.

They may have example of the above. Also if the canvas is not UV protected you are wasting your time & energy.
Sell the canvas & buy the cover….
