So I finally got around to cutting a section of deck off one of the lifeguard rescue boards and trying to do something about the denting and delam problems where the guards kneel. It was a board the town was going to toss out, so I felt like I had some room for experimenting.
After cutting out a big section of the deck, I cut and sanded the foam and stringer down a bit to make room for a layer of 9 ounce 8HS weave cloth (don’t ever use that stuff… it’s such a tight weave that getting the air out from underneath is a real chore), a 2mm thick section of Coremat, and a thin layer of resin with 3M glass bubbles, a bit of Cabosil, and some pigment, sanded flat to smooth off the top of the Coremat and set up a good surface for the top layer of glass cloth. I used vinyl ester resin.
Oh. My. God. I had no idea vinyl ester resin is that hard to sand.
I think I’d need to hit it with a hammer to dent it.
Mission accomplished, I think…
