Ok here is the background - I picked up a beater 9' longboard on craigslist today for really cheap, with the intent to fix it up and have a summer board for next to flat days. Haven't done a super thorough inspection yet, but at first glance it seems to be in ok shape for being 10+ years old, not a ton of pressure dings on the top and the fin box and everything seems really clean. However, I've found at least 2 major dings that go to the core, one on the nose and one on the rail.
Unfortunately the other thing that happened to me today was that I got laid off from work... sucks, but I'd kind of seen it coming and started looking a couple weeks back. Hopefully something pops up soon, but in the meantime I can't really afford to spend a ton of money on this project. Right now I've got a small tube of sun cure resin, plus a few sheets of fiberglass cloth and a quart of evercote premium marine resin left over from an old boat project.
My question is can I use the marine resin/cloth on a surfboard? I feel like I heard somewhere that wasn't good, although if discoloration is the only issue I really don't care. I'd rather get it ride-able then spend more money on supplies. Could I use just the suncure and the cloth? What would you recommend? Also Q-Cell filler - should I get some? At $5 a baggy not a huge deal, but is it worth it? Any help is appreciated, thanks!
Yes to the marine resin and cloth. You're right, it's u g l y. I've done it on an old poly board, have no idea how it would work on epoxy. Yes on the qcell, but I have no idea how that would work with marine resin. The one time I did all this I fixed a deep gouge in the bottom. I cut up fiberglass cloth into tiny fibers and mixed the resin with that. Let that cure, sanded some then put a layer of cloth over it. Cured, sanded, one more hot coat. I fixed that board back in the 90's and 've still got it. Pic of the repair in the quiver thread. Thank goodness my patch jobs have gotten better since then.
Don't use the tube of suncure and cloth only. You can use the suncure as a filler to fill the void before you glass over the dings, if you don't want to go out and buy filler, and if you don't care about cosmetics. The marine resin will work fine for repairs. Prep the area around the dings by sanding down to the weave and removing any loose material. Fill with suncure and use a spreader to get it down into the ding and just below the surface of the surrounding glass... nice and flat. Cut one patch to overlap around the ding about a half inch, and another to overlap about an inch. Let cure, fair, tape off, hotcoat, sand.
