PC Products PC-Marine Moldable Epoxy Putty

Used for above ground pool that had a few holes and it works amazing! It is a little hard to mold into place under water but not too difficult just have to play with it for a few minutes to mold it and get it flat. I used patch kits and nothing worked so glad i bought this because i really did not want to empty the whole pool just to patch the holes. Also worked on the pump hose that sprung a hole. It is very hot where I live 120 degrees in the summer and upwards so its nice to have when the heat burns holes. Make sure to mix until both layers are like a whitish grey takes about 2 minutes just using my fingers.

Works very well and is inexpensive.

This is epoxy rated for wet use, even underwater. Have used both this and 'water weld'. The water weld is a thick paste, so it stays put where you apply it. This is like thick honey, it will slowly ooze downhill. However, in my opinion, this 'sticks' better than water weld. If you have a situation where it will stay in place, or if you can put on more layers to build up where it oozes thin, I prefer this to the Water Weld. It adheres better, and leaves a smoother surface, so you don't have to sand as much if at all to smoothen it.

Fixed a quarter size hole in the in-ground pool stairs wall (above the water line). Worked great. Dried white. Hardly know its there.

I used this product to repair my watering can’s cracked screw on sprinkle cap (very old Rubbermaid watering can so no replacement cap is available). I was able to mold the putty around the outside of the damaged cap and once it hardened, sanded it smooth and re-drill the holes which allow the water to sprinkle out. You’d never know it wasn’t original and I now have a fully functional watering can!

Worked like a charm. Soft and pliable to apply, hardens to concrete strength. I didn't time it, but it was easily cured by the next day. Used UNDERWATER to seal inground pool gap. Was a little tricky to get it from floating off of the concrete surface I was working on, but it did stay after a patient minute. Strongly advise you wear gloves or apply with a tool, because it will take a while to remove the white residue from your bare hands if you opt not to. Regular soap and even garage goop didn't work, (although other compounds might have worked better)

I used this epoxy to fix a stubborn aluminum siding problem. Tried Bondo and other outside products but they never lasted more than a season. The siding is on the hot side of the house and the sun and rain would loosen any fix I tried. It was easy to mold and match the texture of the siding unlike bondo which you have to get right the very first few minutes or forget it. We also have used it to fill in a crease dent on a bumper before painting just to minimize the appearance of the damage. And the original purpose of the stuff was to fix a chip in a white porcelain tub. The only thing that would stay in the chip year after year. The color wasn't a perfect match but a big black chip really looks bad where this stuff was easy to smooth to the tub height and looked better than just painting the chip. Very happy with the product. You can use your fingertip lightly moistened to really get it nice and smooth.
