I've used this, https://www.harborfreight.com/4-piec...set-94635.html
, in a pinch. Its actually been weldwood (red can) glued both onto the top of my drybox and in my kayak as added padding for thigh braces for years. If you can't find the real stuff, it may work. There's a harbor freight in Clifton, but seen similiar stuff at Lowe's.
edit - to late, already on the road.
