Review: makes a great speakerbox. - this worked perfect for building a custom speaker box out of fiberglass, i probably used way more hardener than i needed to as i only have about 20% left with 40% of the resin left but overall i'm very happy with the product, much better price than buying local in quart sizes.
Review: This is a high quality product! - 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.

## Questions & Answers

**Q: Is the 2 oz of hardener provided enough for the gallon of resin?**
A: Yes !

**Q: Hi. Is this can fix soft spot on boat floor**
A: Well......Not if you want to fix it right.  The soft spot in a boat floor can...and usually means the the wood under the floor is rotted and possibly even the stringers.  If you put new matted fiberglass and resin over a soft spot in a boat floor it will most likely crack and bust when you walk in it.  I just replaced a complete boat floor and stringers.  I did use this product along with fiberglass mat to install new stringers and over the top of the new plywood floor.  So far so good but I have not put the boat back on the water yet to see how it all holds up.  Product is fairly simple to use but be sure to use a respirator and gloves.  Good luck!

**Q: Is this resin good for  mold making,  and what's the pot life time?**
A: Very good

**Q: What is the cure time?**
A: Well, it depends.  It is temperature, humidity, and mixture dependent.  Two hours generally is enough time to cure, but I've been giving it 4 hours minimum....often over night.  Once mixed, its very easy to work and getting really good results.  I have not yet figured out the best means to mix it consistently because the varying climatological conditions in my non-climate controlled garage require different ratios.  I will say this though, I love this product compared to other resin products I've used.

### ⭐⭐⭐⭐⭐ Great product
*by R***5 on August 5, 2019*

First time I've ever done any fiberglass work. Nice product great price the only problem is the shipping, although it's free shipping,it's not a prime product so you got to wait 4 or 5 days to get it. UPDATE 8/17/19 I highly highly recommend this product. I originally purchased two gallons of this because I'm redoing the top of my pop up camper. I followed the instructions and this stuff worked great I was able to work with it,rolled on smooth under and over my mat. I need a just a little bit more so I ordered another brand 3_ Bon_o brand. The kind you can buy at your local store or automotive store. Well let me tell you that was a mistake because that brand was junk, nothing compared to this product. The 3_ B_ndo brand sets up way too fast and did not go on smooth. I would recommend this stuff to anybody and I am buying another gallon of it.
