Works wonders. Fixed my porch railing!

I love this product. I have used it as a " temporary " fix for items I could not afford to replace. For example, my garbage disposal had a leak and this works so well I didn't have to replace my garbage disposal. 6 years later still good. My recent fix was the three step aluminum handrail on my front steps. the bottom of the handrail had been bent so I use this to fix it. I waited 48 hours to make sure it was set well. The instructions said something like 24 hours but I waited a little bit longer. I spray painted it with black paint and it looks fine.

Holds as well as an actual weld hol

I really love JB weld it isn't just a glue. It really welds things on. I have used it for things that I wanted to make sure we're never ever coming apart. I used it to put wine glass stem holders up underneath a shelf so I could hang wine glasses under the shelf and it held like cement. It was just amazing and I use it when screws get stripped out. I've glued legs to tables and once you use this glue it's there it's lasting it's not coming apart it's easy to use. It's really neat and it holds like it was welded so the name is very appropriate. I always have some of this on hand.

Excellent to keep on hand

I have been using JB Weld for as long as I can remember. I always keep it around in my shop for those jobs that require a suitable bonding material. Requires 24 hours to attain a maximum and permanent bonding, but when it hardens it's there for good.
