Following up on a previous CF posting
and recommendation, I used Oakey x-15 Shower
Pan Liner Adhesive
to attach seat pads to mt Zodiac
I stood on the seat to provide professional industrial standards testing (more than 200 lbs.) and the seat held firmly.
(I also repaired a leak--1/2" hole--with
a pvc patch and X-15--holding up well under full pressure.)
I'll follow with an in-water test (which should actually be easier on the seat) next week.
I used HH66 last year on the loose seams, but final testing is needed.
I know that trying to repair seams can be frustrating and perhaps futile, but
I'll try the X-15 if the HH66 fails.
