Seagull poop ate holes in the cotton denim skin. Then the seagulls pecked at the holes to see if it had tasty guts. They pecked right through the closed cell foam layer. Now you couldn't use the boat at all without getting a wet butt.
Ray and Chloe volunteered to make a new skin.
Step 1: Old and Broken
Peel it off, exposing the closed-cell foam layer underneath.
Step 2: Patch the Big Hole
Then she cuts a piece of foam to match the hole and glues it in using DAP weldwood contact cement.
In this case we didn't follow the directions and glued it in while the glue was still wet. The shape holds it in place and it would have been impossible to insert the plug after the glue got tacky.
Step 3: Patch the Stems
Then I used the turkey knife to smooth the edges of the patch.
