Polymer World- Polyester Resin .75x50x5 Yard Chopped Strand Mat, Fiberglass Kit for Boats, Cars, Surfboard, RV, Canoes, Jetski, Watercraft, with MEKP

If you follow the instructions this is a great product. I did it outside in the shade on my tractor cab that had a hole and several cracks from a tree limb hitting it. I measured and pre cut the mesh. Had it all separated and laid out. Don’t mix but a couple of ounces and don’t mix until you have EVERYTHING ready. You will have approximately 10 minutes to apply. Get extra cheap paint brushes as they will harden. Watch videos on U Tube before trying if you’re a beginner. Saved me 1500$ and I put 3 layers on in 1 hr. Rained heavily 2 days later and no leaks. Painted it the next day Photo is before and after

Very good material, exactly what I was looking for. My project is finished, just ordered more than I needed.

I like the combo kit.

Why did you pick this product vs others?: Very good price point. The only issue was the amount or hardner. I had to buy two more tubes. It only came with one small one. It was not enough for the entire gallon.

Used this to glass in 4 boat seat bases and I have tons left over. Great stuff

Buildings a water fountain and it made it easier

Product had a good long working time. It is a little runner that I expected but once fiberglass is saturated, it holds in place. Smell of product is very strong. Glad I bought a new respirator. The amount of hardener given seems a little short and will have to buy extra. Maybe it is the perfect amount if you mix the whole gallon at once but I will be doing around 10 mixes for my subwoofer enclosure. I like the fiberglass included because it doesn't make your skin itch.

Used it to reinforce a weak floorboard section in a 50 year old car. There were a few pinholes showing through, but floor was basically sound. So I sanded the interior side of the floorboard down, and applied 3 separate layers of resin and fiberglass mat, to seal, strengthen, and protect the floor. I used a stiff, cheap disposable "chip brush" to brush the resin into the fiberglass mat, and press the mat down. Just lay the mat down on the surface first, and brush the resin through the mat. Resin and hardener work fine, unless it is a really cold day... Then, you must use a heat gun, or space heater to get the temperature up to normal room temperature, so that it will harden. Because the kit I ordered uses the random strands of glass (fiberglass mat) it is much stronger than the fiberglass cloth. The amount of hardener included, was plenty enough to harden the gallon of resin. Just use the amount of hardener recommended, don't try to over catalyze the resin by using too much hardener. I used a disposable plastic measuring cup, to measure out each resin pour. Be sure to have good ventilation, and a pair of disposable gloves are a great idea.
