Premium Polyester Resin w/Hardener for Laminating Fiberglass mat, biaxle, Cloth (Quart)

Great customer service as always.

The resin came with a meshing cup for the hardner it was a very nice touch, when I finished I put every Bach in the ziplock bag it came in.

Didn't know it took longer to harden

My first test batch of one ounce with 10 drops of hardener. failed to harden in a reasonable time frame. A full cure required over 12 hrs. All other batches were mixed with 14 to 16 drops per ounce. With that mix ratio range this product performed flawlessly setting up tack free!

Like some other reviewers, I found that this didn't set properly. After 72 hours, it's still tacky and soft enough to be scraped up with a fingernail. I'll need to remove the faulty resin manually and use some VOC to clean it up.I've used tons of polyester fiberglass resin for restoration and repairs and I'm deeply familiar with how to measure and apply it. Due to some manufacturing or storage issue, this was defective. In any case, Amazon - as always - stood by this product and provided me with a credit which I used to buy a different brand of resin.

Big sticky mess. Seller needs to make sure cap is sealed. Received a leaking bottle in a plastic bag. Was able to use a little of it, doesn't really set up hard like some Polyester Resins, so the part I made was still a little bit flexible.

Came quickly. My use case was odd, I was stabilizing a shepherds crook pole in a bed of gravel. For thispurpose, it worked very well. It does produce annoying fumes but that is a characteristic of all such resins.Good stuff!

Product was not what I needed
