I need to fix some velcro to my cockpit seat so I can keep a skwoosh
pad from slipping around. I notice that some manufacturers that make
accessories for kayaks include adhesive backed velcro for this purpose.
Any off the shelf product I've tried very soon becomes loosened and
unattached by sea water. if you have had luck doing same, what did you
use?

My local kayak shop sells a contact cement (apparently rubber based)
specifically for this (plus foam). Works great!
