Comstar 10-801 Copper Lock, No Heat Solder, 10 mL

Pegamento fuerte y fácil de usar, resultó mejor de lo que esperaba.

My 2008 Yukon had one read defog tab ripped off. I tried a product from a store specifically to 'glue' it on - no good - completely disappointed. I used this in with a piece of copper tape which I got on amazon. The copper tape is conductive on both sides - yes - including the sticky side. Clean the area on the window so there is no dirt. I used a 1.5" long piece of conductive copper tape and taped it over the area on the glass where the tab is supposed to go. Rub the tape firmly on the window. Then, I used this product to 'glue' the tab to the copper tape I put put on the window. Prepare the tab by sanding it so it is shiny copper. I poured a thin layer of the red liquid on the back of the tab and placed it in place on the copper tape. Apply good pressure for 2 whole minutes AND DON'T MOVE IT. It stuck. I let it be for 10 minutes and then gently and carefully placed the electrical connected on the tab. I turned on the rear defog switch and used a multi-meter to determine there was voltage on the window. There was..and it works. It's too bad that they don't sell a smaller bottle. I only used about 15 drops in total. Good luck to you.

I replaced my gas water heater and needed to reattach the copper overflow pipe from the pressure release valve. I don’t have experience with copper solder so this was a great alternative. Very easy to use and appears to be a solid bond. I honestly don’t know if I would trust it if the copper pipe was under constant water pressure but for my application it is perfect. If the pressure relief valve pops and water flows into the overflow pipe I am having a bad day and it isn’t going to matter if the pipe leaks a little!

Great product. Life saver.

This creates a seal within copper fittings-- aka pipes into couplers. Works like a champ for connection copper water lines without soldering. It will not adhere brass to brass. It is not a glue, rather it is a seal that forms after setting. That is the only reason I didn't give it 5 stars.
