Q: Can you use this on automotive radiator

a year ago
1 Answer
  • A: Look to our 2120 Radiator kit for this. Be sure to have the included mat cut to size before you mix the epoxy. You will only have about 2-3 minutes to mix and apply the epoxy before it starts to set. Mix for no more than 1 minute. Apply before the mix starts to get warm in the packaging which means the epoxy is starting to cure. Contact us at jbweld.com for anymore help needed.

WATER TROUGH LEAK FIX THAT WORKS

5 years ago
This stuff works and is easy to apply - I have troughs that the leak fix has held in years - some cracks were as long as 4-5 inches and some also had small holes - this stuff has held on Rubbermaid 100+ gallon and 50 gallon water troughs AND works on the recycled water troughs as well According to the packaging it is drinking water safe

Most Helpful Critical Review

Good product, horrible package

5 years ago
I used it on a cracked area in my tub surround shelf. Seems to be working very well. I gave it 3 stars, though, because the tube it comes in is so flimsy, that when it rolled off the edge of the tub, the tube shattered. Now it is very difficult to keep it sealed enough that it dries out very quickly. Didn't use much the first time, so the majority is wasted. That's a shame.

This stuff works!

9 days ago
We've had a few tubes of this stuff on the shelf and never used it until last week. I finally found a need for the waterweld, so I cut a bit off and started balling it up in my fingers until the consistency smoothed out, and I put it on the tank. Only issue is I was in a rush, and didn't get rubbers on, so I've been wearing this stuff on the tips of my fingers, now for week, slowly chipping it off. My only real complaint is the smell. My hands smell like me and my ex linked up again, so definitely glove up if you use this stuff. As for the tank I haven't given it a look to see how its doing, but it holds water now do I reckon its working pretty well.

Yes, I recommend this product.

My friend put some on a tooth that had a crack in it and hurt really really bad. He had to let it sit for a little while before applying it but once he got it on his tooth he felt better! I guess it kept the nerve from being exposed or getting food on it. It did come out on its own after a few days so he's going to get some more and do it again but his friend that told him to do it stayed in for like three years! It's the craziest thing I ever heard but hey it might be useful info for somebody, all though of course I am not a dentist or doctor so I'm not recommending. We all make our own choices...

Yes, I recommend this product.

I had a pin hole leak on a copper pipe. I cut a piece, kneaded, and applied it to the leaking pipe using a hose clamp to keep in place. Within a few minutes the leak stopped. I dried the area and checked back 8 hours later and the area was still dry. It fixed the leak without having to cut the water off to replace the copper pipe.

Yes, I recommend this product.
