## Questions & Answers

**Q: Will this epoxy work  on plastic fuel tanks?**
A: Yes, absolutely. We've used it on pressurized fuel tanks too. Fixed punctures, even cracked threaded connection collars. This is the best epoxy we've ever seen. The key is all in the prep work, using 80 grit as instructed. Once the plastic is sanded and prepped, for added strength it advises "curing" the plastic before applying epoxy by heating that sanded plastic area with a torch (flame). Clearly this step can be dangerous, do only if it's an empty aired out tank. Otherwise skip this step. Prep, prep, prep is the key.

**Q: does it work with wood?**
A: Yes, but the regular epoxy works very well with wood and is less expensive.  I bonded plastic to wood with this.

**Q: Will this epoxy work on cement steps**
A: Not sure how you're proposing to use it exactly, but it's a great product and will work on virtually anything.

**Q: What type of prep work is needed if i'm using this on a scepter water jug? light sanding? i'm trying to glue an abs 6x12" plate to it the jug.**
A: Sanding for "Tooth" and then a "Degreasing " on Both Items (jug & base) I use denatured alcohol.  I'd  lay the Jug Base down into the Gflex and let simple gravity do the joining. Hope this helps

## Customer Reviews

### ⭐⭐⭐⭐⭐ Superior product
*by F***R on January 19, 2025*

Sticks to anything. Used it to seal the bulkhead on my 16.5’ kayak front bulkhead. It is made of ABS plastic. This epoxy exceeded my expectations, was recommended by the reps at Hurricane kayaks. Easy to work with, dries hard as a rock but flexes with my boat. I use my kayak 50+ times a year. Worth every cent

### ⭐⭐⭐⭐⭐ Abs 2 man boat repair
*by F***N on July 28, 2024*

Great product. I used it to repair a crack in my 10 foot prowler boat. The crack was horizontal about 10” long including an inside and an outside bend. I watched a how to video on utube? Followed the step by step instructions and had the repair patch done in fifteen minutes. Let it dry for 24 hours and put it in the lake. Two of us fished out of it for two days. Worked great. I would highly recommend this product if you’re looking for a permanent patch for a abs plastic boat. This product is meant for underwater use.

### ⭐⭐⭐⭐⭐ Good glue
*by M***. on May 18, 2019*

I bought then to glue a 3" uniseal to polyethylene, and ended up gluing 2 one side the worst damaged side of the polyethylene glued well and is sitting under pressure underwater now, however the other side which I damaged in the process of taking everything apart to glue the bad side Did not hold completely near the bottom of the seal it separated slightly, although i suspect it had to do with the preparation since it was my first time I probably did not get it 100% right, although It's also underwater and not leaking. To add my neighbor fixes cars and was looking for a new glue to use for repairs he took the piece of card board I mixed the glue on and attempted to crack it only causing him frustration, and eventually just cutting it with my big pick axe lol, he says it wont crack and the look on his face said I don't understand. I would buy this again, I have also used it to repair my Nike sandals which split all way through on the side of both sandals as well as the top strap starting to come loose from the rubber, But it was no problem for this glue. I have size 15 foot, and often end up catching the front of the sandal on stuff bending it in half at times as i step forward with 250lbs behind my step, but no cracking or damage at all since glued i am surprised.
