I am looking for ways to fix Velcro straps to the hull of a Kevlar Sea
Kayak.
The straps would be to secure lead ballast and other gear
I am thinking of using thickened epoxy or contact cement

I think you will be bonding to whatever resin was used with the Kevlar, or
perhaps a gelcoat or paint over the resin-Kevlar, rather than directly to the
Kevlar.

Provided the surface is reasonably smooth and clean, I think a
non-water-soluble contact cement will work well. I use contact cement to glue
neoprene strips to gelcoat (or the underlying epoxy) on the gunwales of my
small sailboats (a nice material to keep the trapezing crew's feet from
sliding).
