Review: "Wow! It’s only 30 degrees out side" And it Works.... - "Wow! It’s only 30 degrees out, but after hitting hard ice and chipping my front bumper, this stuff saved me. All the inner plastic clips had snapped off, leaving my bumper dangling. I used the black plastic weld, held it in place for 30 minutes, and now it’s rock hard. I highly recommend this product!"

## Questions & Answers

**Q: Is the final color actually black?**
A: It is matt black when dry....

**Q: My hardshell bag was slit during handling - 2", sides could be fitted together.  The shell has give in that spot. Will it hold up to baggage handling?**
A: If the hardshell has some good years of use ahead, I would give it a try. My experience with the product is that it held up very well in repairing a cracked  door that gets a good deal of use. How it will hold up depends on how well the material is applied and how much rough handling the bag gets, among other things. Good luck.

**Q: Is this product heat resistance?  I need something to repiar holes in a plastic solar water heater**
A: I used this on some hub covers of my truck lug nuts.
it is very hard when cured. Only good if fresh shelf life bad.
make sure you ruff things up to bond to your piping or what ever.

**Q: can this be used to fill in deep scrapes in a bumper?**
A: I don't think I would use it for that. This epoxy will harden to a durable hard plastic, much like ABS. Although it does have some elasticity it's really designed for more rigid applications than a typical bumper cover. This is great for repairing things like cracked or broken plastic as might be found in car dashboards or appliances. It could even be used to rebuild areas that have missing areas.

### ⭐⭐⭐⭐⭐ Be Certain Before Applying, It Will Not Come Off!
*by C***R on July 17, 2025*

Stinks to high heaven, but is set in 5 minutes. Messy to use if you are using their little stick to apply the epoxy with. I ended up using a small plastic putty knife, and it worked like a charm for the area I wanted covered. The one side will continue to come out the plunger even after you stop pushing on it. Be ready for a mess it you don't cap it off quickly. I used this on a pvc wall panel and a corner joint. Worked perfectly and is very sturdy. I wish they had a better applicator for this product.
