Works best when you leave It get hard overnight

It works really well for pvc

I smeared it onto the bottom of a humidifier. The plastic basin had a large crack through it. I can't believe how well this worked. Worked great.It comes wrapped in cellophane tho and I found it impossible to get a little bit out so basically used the whole thing for a small repair, I found another 'thing' in the basement to use the rest on but...yeah. All in all, whatever, 6$ to repair my humidifier is worth it.But at least it wasn't dried out...

I used this putty to seal a 1/2 crack in plumbing (cast iron drain pipe). The crack was 1/2 wide and about 3 long (it was a big crack!). I took out wire brush and attached it to drill and sanded down the cast iron down to the metal. Atter sanding, I cleaned the surface with isopropyl alcohol. I then mixed and applied the putty to the crack. The putty was even applied to the crack as water was dripping down from the drain pipe. It took a few minutes of manipulation with my fingers to get it to stick to the surface (and to push it in the crack as water dripped. After making sure it was securely applied, I left it overnight and the following day, I came back and it was rock hard, water tight, and no more water leaks. Keep in mind that this was used on a drain pipe (no pressure) and for that application (on cast iron pipe), I give it 5/5 stars so. Will see how long it holds up.

Used it to secure a shower that had come loose back to the wall. Awesome stuff!

Works just as it should. Everyone should keep some handy in their tool chest.

I was happy to find this in an off white for our metal door which had some tiny holes due to the curtain rod which I removed. The putty dried hard after some time and worked very well in filling the holes.

A little hard to mix but that goes with the territory. Use gloves, it's messy. Makes a very hard finished product. don't know about removal, my repairs were permanent.

Good

Not much to it, tear off some, rub between your fingers and apply. Seems to work as touted

I've used JB Weld products for years and swear by them. This one is no exception. Easy to use and easy cleanup. You can use it in wet or dry conditions. The best part is that it really works!

Used it to seal a crack on the plastic housing on the windshield wiper fluid reservoir on my car. No more leaks!

The only product I'll use for underwater applications.
