This is a high quality product!
C. Williams✓ Verified Purchase•August 27, 2023
I originally bought a gallon of this for my first ever fiberglass project. It wets out the mat quickly and laminated layers go together without problems. I ran out and didn't want to wait for more so I went to the big box store and bought the 3_Bon_o brand that you can get everywhere.
Whoa, that was a major mistake! For some reason it took a ton of effort to get it to wet out the mat and even once it did for some reason it doesn't stick well. I spent a ton of time going back over spots where huge air bubbles formed for no reason at all. Often more than 5 times on the same spot. It also gelled very quickly compared to this brand. I had to go back with a grinder to get all the bubbles out of my work. I stopped using it and just ordered some more of this.
I know now for future projects I need to get a higher quality product because it's now apparent that not all resins are created equal. Guess I got lucky on my first try and I recommend this to anyone else wanting to do fiberglass work.

Not enough hardener included, but it did work great for me

I have used fiber glass resin quite a few times. So I think I know what I am doing but the instructions for mixing up is just very Vague. There is also not enough hardener included with the gallon. I need to buy more so I can use the last quart and a half that I have left.
Does what was intended to do

This sets up fast depending on temp so start out with a small batch like 8 ounces and work your way up. A good respirator is a must! Mixing ratio I used was 1/2 a cc per ounce so a 12 ounce batch would use 6 cc's of catalyst. If u have lots of detail or corners and curves get a batch of chip brushes. Plastic spreaders work well on flat surfaces.
Does whats needed, and works well with the hardeners.

Works well
Thin resin impregnates fibers easier
Kylemcweeny✓ Verified Purchase•July 15, 2023
This resin is thinner than most. (You can thin resin with acetone too). So it applies easily. Plus it's very transparent so that's great to know that you fully wet the fibers because you can see what's behind it. Hardener cones with extra so you will run out of resin before hardener.
