Description

See the resin, fiberglass cloth, filler and accessories included in this repair kit. Explore the epoxy resin, hardener, reinforcement materials and bonus SunCure tube. See the resin, hardener, fiberglass cloth and mixing supplies inside the kit. Take a closer look at the epoxy putty stick, sanding pad, wipes and applicators. Get a closer look at the cloth’s woven texture as it comes out of the package. Remove wax, dirt and loose material. Let the area dry completely, then sand around the ding. ix 2 parts resin (A) with 1 part hardener (B). Stir well, scraping the cup's sides and bottom. Place fiberglass cloth over the prepared area. Wet it with mixed epoxy and smooth out air bubbles. Allow about 6-8 hours at 77°F. Temperature affects cure time. Follow the kit instructions. Once fully hardened, sand the repair to blend the edges. Inspect the repair before use. Real customer photos show a damaged surfboard nose before and after repair. Nose Repairs Cut cloth to fit a prepared nose repair. Missing foam may also require a suitable filler. Tail Repairs Add fiberglass reinforcement over a prepared tail repair using compatible resin. Outer Skin Damage Use cloth and compatible resin to reinforce prepared areas of damaged outer fiberglass. Curved Edges Pliable cloth follows curved rails to reinforce prepared repairs with compatible resin. Which resin should I use on an epoxy board? Choose an epoxy-compatible repair resin. Do not use polyester resin on exposed EPS foam—it can damage the foam. Can I use epoxy resin on a polyester board? Yes. Ding All epoxy repair resin works on both epoxy and polyester surfboards. Do all repair kits need sunlight? No. Resin mixed with hardener cures without sunlight. SunCure resin, including the bonus tubes in Super kits, needs UV exposure. What is Q-Cell filler used for? Q-Cell thickens resin to fill deeper dings and missing foam. For resin-and-hardener systems, mix the hardener into the resin before adding Q-Cell. Is working time the same as cure time? No. Working time is the time available to apply mixed resin. Cure time is the time needed for it to harden. Follow your kit’s instructions before returning to the water.

Dings fixed
Size: 8 Oz
Better instructions on mixing ratio is needed in the resin kit in plain English. The resin works but was nervous about it curing correctly!

Easy repairs
Size: 1 Quart
Please take caution with any chemicals pretty strong smell the function part was a miracle to be able to mix and sand. In my case with Qcell depending on the # of catalyst drop it take little longer or fast to dry depending temperature too. at 90 degrees-5 drops catalyst, I let it dry over night and was solid on my board lite and almost very strong. That was cool😎 ... show more

Customer service came through
Size: 8 Oz
Seller sent Sun Cure initially when I ordered the sanding resin. If you repair your own boards you know the difference. When I took steps to return the item they got in touch immediately. Told me to hang onto the Sun Cure and they would ship the Sanding Resin. Said something about there was the same ordering info for both on the Amazon listing. It was clear to me on Amazon. The Sun Cure had its Red label packaging photo and a different price. I was charged the correct Sanding Resin price, had selected the Blue Label Sanding Resin photo package and the packing slip and order documentation stated Sanding Resin. Hope they straightened that one out with Amazon. After the prompt message to replace my order, I didn't hear anything for 2 weeks. Made another return request to Amazon, was promptly contacted by seller and assured the item would ship immediately, which it did and received the correct item in a couple of days. So happy end to a slight mixup. ... show more

Great Service and Product
Size: 8 Oz
I initially received the completely wrong item from this seller but they got back to me quickly and gave me a replacement fairly quickly, hence the positive review. The product itself works great for making small and moderate sized repairs on my surfboard.

Lasted a full year!
Size: 1 Gallon
This is good stuff. I bought this May 4, 2018, buying another one July 14, 2019 because I finally ran out. I repair surfboard as a hobby and I have been able to do so much with this gallon. As long as you know what your doing there isn’t a racking issue like other review have said, you just have to add enough Catalyst to the resin. ... show more
