I put a wall made of fiberglass in the pointy bit at the front where its just a pain in the ass to get to. I got two screw lids off ali and i can glue the collar into the hole and have a nice neat screw lid to the waterproof space. Its called a bulkhead. I do a little bit at a time and let the fiberglass set, then I sand it back and plan the next little bit. Its a good strategy, I can make them really strong and neat. I have four of these bulkheads to do. The one in the middle I wont have access to but it will block off the space under the seat there, so when its upside down in the bush, the dasturdly possums wont sleep there and gank it up. I have to put a skin on the bottom and then patch it where its broken too. I want to paint it from orange and white to brown and green. Its actually gonna cost me a lot. I paid the boys across the street $150 and at least three times that in resin and matting. Oh well. It will be ten times better than new. I am like a samurai of fiberglass, I strive for perfection while I huff neruotoxic styrene fumes. Loool.
