We have some little holes from bonfire embers in a 16ft tramp, we're a bit far from anywhere to take it in for repairs. I see people have used Stormsure adhesive and patches (e.g. https://www.marine-deals.co.nz/watersports-accessories/stormsure-instant-waterproof-adhesive-repair-patch-75mm-qty-5 ) but do you have any tips for a more economic option? Or would that be my best bet?
