Cut the deck off and reglass not always an option for those on the budget speed speed get it back fast plan with knee paddling delams.
Injecting resin alone is so… boring. Don’t you have something better to do with those weights than to, ew, push the glass down?
A little vinylester, some milled glass fibers and microballoons, and a VW Touareg air suspension pump…
How well did it work?
It’s a little tricky to get the deck to pull down evenly on some of these I think because the fiberglass is all stretched out of shape from being bubbled up so long. The resin likes to kind of pool around the perimeter of the delam and squish out of the center. So I had to work it flat with my fingers while the vacuum was pulling the deck down. Second one, I pulled the deck down with no resin inside it and used a 150 watt flood lamp to heat up the fiberglass until it got a little soft and let it kind of smoosh back to shape, then cool down while still being pulled down by the vacuum. Release vacuum, inject gooey stuff, and pull a vacuum again.
They came out okay. I’ve done 5 like this in the last few days and the decks feel nice and solid again. The real test will be when they sit out on the beach in front of the guard towers and get the full treatment of hot sun, cold water, knee paddlers, stomping little kids, all that good stuff in rotation every day for a couple months. They’re working boards, so a little extra weight isn’t really an issue, as long as the repair is cheap, fast, and durable. I feel better if it looks good too.
