Messy for me but works great!
Needed this to hold a concrete anchor in place and it worked great! Dried fast, holding well; the only problem was most likely user error. I had a difficult time being neat about mixing and placing the material, which meant that I wasted more than intended. Oh well

Worked like a charm for securing some pvc pipe to a trolling motor pole in order to make a livescope boat mount. Water sealed, no wiggle. Feels really durable.

Works perfectly. Highly recommended.
I have used JB Weld over and over for years. I have repaired my vehicle twice with it because I couldn't find parts for replacement. It works perfectly. I couldn't ask for anything more. I try to keep it on hand always.
