Review: Excellent product - I love this stuff. Good price, have been able to fix everything I ever tried to fix with it. Dries quickly, not to messy, sticks to everything. Very strong.
Review: Be Certain Before Applying, It Will Not Come Off! - 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.

## 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.

### ⭐⭐⭐⭐⭐ Worked better than I expected
*by R***A on November 4, 2019*

This stuff works great on ABS plastic. I used it to repair a cracked radiator fan shroud, which has split about 3/4 down the side. I had some reservations, based on some of the other reviews - as well as a review I saw on YouTube by the Project Farm guy. However, I decided to give it a shot and see how it worked. I started by cleaning the plastic shroud with isopropyl alcohol, then used a little brush to make sure the plastic was clean. I then mixed the glue on a paper plate using a little popsicle stick. I think the trick to this glue is to really mix it well. I read a lot of other review were people were complaining that the glue didn't come out evenly or it didn't work. In my case, the glue came out just fine, but if one side or the other is coming out al little more, you just have to shift the pressure on the plunger over to the other side to help equalize things. ** Very important: make sure you remove the built in stirring stick from between the plunger part, otherwise the it's hard to get the glue to come out smoothly. I mixed the glue up really well.. all back and forth, sideways and up and down. Then used the stick to spread it over the ABS plastic of my radiator fan shroud. I used 2 or 3 applications, but even just the first one did the trick. I was totally dry in about 30 to 45 minutes when I checked. It even glued to the wood (the stick I used to mix) and the paper plate. Those two ended up bonded together for life. So it's pretty impressive how fast it setup and how well it worked on the plastic. After applying the 3rd coat, I put some force on the plastic shroud and it didn't budge. I have to give this stuff 5 stars. It setup quickly and seemed to bond very well to the ABS. I wasn't expecting it to work as well as it did actually. It's a plus that it's a nice solid black color also, as it matches black plastic parts a lot better than some of the other glues out there.
