Review: Awesome - i use this stuff in crafting and i gotta say it works great. super easy to use, just mix parts A & B. it dries to a very dark glossy grey. its smooth and is very durable. i find that it holds the joint very well. these are small tubes but go a long way, plus the price is right so its all a win win
Review: Inexpensive quality fix - Bought as a YouTube way of do it yourself fixing of worn wear ring on my jet boat. Saved hundreds, improved power and reduced temperature. Takes time and patience, but again, saved hundreds.

## Questions & Answers

**Q: How hot can this get and would this work in a engine block sleeve  (this were the piston goes up and down ). Its for a 2 stoke 80cc dirt bike ?**
A: If the glue is to be placed on the inside of the sleeve to cover a defect where the rings pass over the repair, this is an extremely demanding use and liable to fail. I'd use a dremel to grind an undercut "dovetail" in the defect and apply J-B Weld High Heat epoxy putty. About 500 degrees max.

**Q: My deck screws are no longer biting to secure deck on boat. What product do u recommend to fill hole and redrill?**
A: I just finished filling holes in boat deck that no longer would hold the screws. It dries white. I filled the hole and after curing time I redrilled the holes and mounted the lids. Held up fine so far

**Q: Can I use this product on acrylic plastic?**
A: No, you need to use the JB Weld plastic bonder, item 50133 or 50139.
Thanks,
JB Weld Support

**Q: Is this product uv resistant?**
A: "I'm confused, the product description says it is UV resistant."
Let's rewrite that (pretending that we have a sixth-grade education):
"I'm confused; the product description says it is UV resistant."
Unfortunately, the J-B company is  using the name MarineWeld for two very different adhesives.
The white kind (in syringes) and the gray (in squeezable tubes) differ in much more than color.

### ⭐⭐⭐⭐⭐ Great for Repairing a Fountain
*by I***T on April 18, 2025*

I have a multi-tier, resin garden fountain that is around 10 years old. They don't make that fountain anymore & similar ones are 4 times the price now. I can't bear the thought of having it dumped in a landfill either. So every spring I check the fountain for hairline cracks & tiny holes using a flashlight. This JB Marine Weld makes it easy to repair those spots. I let it dry overnight, touch everything up with a little spray paint and the fountain is functional again. For larger holes, pliable screen netting can be cut to shape and then covered over with this welding paste. It dries solid and is alot stronger than you think. Highly recommend this!! Lots of possible uses with a little creative thinking.
