ok i am back to say that the leak stopped.
I love JB Weld products, but this putty did not work on a pressurized pvc pipe with a tiny pin hole drip. I sanded, wire brushed, cleaned and dried, mixed putty wrapped it on pipe smoothed down edges and it started making bubbles under the putty. I knew it was not going to work then, i kept soothing it out trying to clog the pin hole, i let it sit for an hour checked and it is still dipping. Gotta get some pvc parts and get to work. IM sure it works for some applications, not with active drip I gave it an hour and checked back it was not leaking, two days later still not leaking. JB weld is good stuff.

Excellent watertight seal
I used this seal a chest freezer to convert into an ice bath. Worked perfectly over a year and no leaks. I needed like 20 tubes of the stuff so I wish it came in bigger amounts, but best product out there. Use latex or nitrile gloves and if you keep your gloves moist it is easier to apply.

A Must-Have for Emergencies
The day before a week-long trip, my wife tells me the kitchen sink is clogged. Not what I want to hear at 10pm the night before I have to wake up at 4:30am for an early flight. So after using the plunger and then the snake, I finally clear the grease clog enough that I can go to sleep at 1:30am.I get home a week later and I try out the kitchen sink by washing some dishes as a test. Great! The water went down. Then I step out to the garage (where the waste line runs through) and find rivers of water trickling all over the floor. After moving the washer and dryer out of the way and knocking out a foot of concrete around the waste line, I find water pouring out of the galvanized pipe through a corrosion hole. Apparently, the hole was being covered by the built up greasy sludge and the snake moved the sludge out of the way, allowing all the water to run down the concrete block wall. As I was contemplated popping a new hole though the wall and into the kitchen cabinet so I could run a temp PVC line (I am redoing the kitchen soon anyway), I realized I had bought this J-B WaterWeld Epoxy some time ago “just in case”. So I thought “what the heck” and tried it out. Worst case, I would have to run that new line anyway. Well, s—fire if it didn’t stick to that galvanized pipe and seal that hole! Even though it was still dripping water, that patch stuck and cured in place just like the packaging says. I had to use a second patch because it was still leaking from somewhere I couldn’t see and that second patch sealed the deal. Now, I am treating the line with some Green Gobbler Enzyme to keep the sludge at bay until I replace everything in the kitchen reno.A couple of tips:1. Clean the area first with a degreaser, as the packaging says. This was essential to me because all sorts of cooking oils had been coming out of that hole and you need that stuff to stick.2. Use a knife to cut only what you need and mix it in your hand using a glove. That stuff is very sticky and won’t easily come off your fingers.3. If patching a hole, form a patty after you mix it and apply and them smooth the sides of the patch. It will mostly retain it’s form and get rock hard in a few minutes.4. Finally, don’t wait too long to apply. You have a few minutes to apply it, otherwise the chemical reaction will start to harden it and it won’t stick.I am so glad that I had this stuff on hand. It saved me a full day of breaking concrete block and fitting a new temp waste line. You can see the patch at the bottom of the pipe. Because of the location, it had to be done by feel and I did take off the glove. But it wasn’t so bad after it had been mixed.Update 8/23/22: After 6 months the patch is still holding strong with no leaks. That’s a relief considering the kitchen reno is taking longer to get started than expected. But that’s another story…

It works, but itâs messy and tricky
I like this product, but I would give this 4.5 stars instead of 5, because this was a bit tricky to use..Instruction says, âThoroughly knead putty with fingers to a uniform color.â I would think that this means that you have two different colored ingredients to knead? That is NOT the case. The putty is gray in color. You canât tell from color alone that youâve kneaded this thoroughly..You can tell that youâve kneaded thoroughly when this putty becomes pasty and starts sticking to your gloves. This starts out as putty like, then becomes pasty, and then starts drying/curing back to a putty like state before eventually hardening..TIP: get plenty of snug fitting surgical type gloves. Any putty that becomes pasty and sticks to the gloves will become unusable. And you will need to swap out gloves and start again. You have to scrape of what you can, shape it, and apply it. And after applying, when a couple of minutes before you start to shape the putty and seal the surface..ANOTHER TIP: Use a scraper or a tool to pick up the putty and to apply it. Itâs like applying speckle..Curing takes longer than 1 hour. Iâd say at least 2 hours minimum at room temperature before you stop noticing any ârubberinessâ..Putty is gray to start and turns off white when cured. This part is true.

Was going to throw out a $200 cracked rain barrel. Then I found this stuff and gave it a shot in fixing the crack. It setup fast and worked.
