Fiberglass Supply Depot White Gelcoat with Wax – UV-Resistant Marine Gelcoat for Interior & Exterior Use – Pint Kit with 15cc MEKP Hardener

Quality product.

I used this white gel coat with wax to repair deep scratches from dock damage on my 23' sailboat . Per the instructions, the gel coat container was shaken well to ensure wax completely mixed with the epoxy. The gel coat epoxy and hardener were then measured and mixed together per the instructions. I sanded and cleaned the damaged area previously and applied the gel coat using a 1/2 inch water color brush. The bright white finish is smooth, hard, and matches the original hull color very well.

Old boat, look like new hatch cover

It's tricky ordering gelcoat online, and while this gelcoat did all it was supposed to, you have to make sure you understand the size you are ordering. I've read that some have been fooled by the image and ended up with too little for the job. I didn't make that mistake, but the company here isn't very helpful in other areas. The package only included a small instruction, and failed to mention that the gelcoat would eat a Solo cup. I kinda made a mess. Also, make sure you understand that you can't tint the white very well. I got purple. Oops.

Great product. I used this on a canoe patch to protect the fiberglass. It has a rough finish and is kind of goey so if you use a brush or roller it will leave a pattern. I don't care about looks I just wanted to protect my canoe and it seems very durable.

This was my first experience painting with gel coat. It went on very well over fiberglass as well as pre-existing gel coat that had been sanded with 80 grit sand paper. It wasnt runny at all and went on thick which was nice on the vertical surfaces I painted. I did not realize how fast the gel coat would thicken however so I wasted a lot of it. 1 pint goes a long way if I mixed it correctly. I'll update this review once I sand it down to be smooth.

product was runny. Added hardener was spreading good then started to clump up. Mixed a second batch worked well. I'm sure outside airtempature and humidity are a factor. Overall great product

Product took more than a day to harden. Hardener was precisely measured using a syringe. It was applied in several thin coats and lightly sanded between coats. I was after a textured surface so it did not bother me that it did not flatten much when applied via roller. However, if a smooth finish is sought, this product did not perform well. One would think that a slow setting product would flatten better, but it clearly did not. THat said, I was happy with the final result as the textured fiberglass surface serves me well and remains hard, low-slip and stain free.
