Seam leaks

[Keystoner]

Has anyone used "HH-66" vinyl adhesive to seal the seams?

My 2014 Shamrock 21ss bunk seams still leak after the ends were replaced, seasoned, and back to the dealer. (That's a total of 3 trips to the dealer for a total 9 months.)

Veada made the vinyl fabric and when contacted about how to better seal the seams they generously apologized for my troubles and referred me back to my dealer.

Wife and I are tired of waking up with wet pillows and sheets wet down at our feet.

I would get some bricks of bees wax and rub it in the seams, should do the trick.
