I use it in my car restoration business for many different things and it has always been satisfactory. It will certainly stand up to the hot water temps as we use it in sealing coolant parts where the temps approach 230 degrees. It sticks to most anything, but I would probably use a small piece of sandpaper around the edges of the crack to both clean it as well as rough up the surface to give it something to bite on. see less

Q: Can I use it to glue shower mirror to tile in my shower

A: You can but it will probably leach through the mirror coating and appear as mold. Buy mirror mastic.

Q: Can you remove it if needed?

A: Believe the instructions are on the back side of the package. You can use acetone or paint thinner to remove.Its great stuff. Works well.

Q: Can I use this to seal the hole of my clay pot for a water fountain?

I've used it to repair broken aquarium decor pieces and they're still holding. It's rather nasty stuff to work with when wet, but once it cures (24 hrs in ideal conditions), it is nontoxic and impervious to water. As for applying it under water, probably not. I've never tried it, but the directions say to CLEAN and DRY the surface before application. see less

Q: Puedo usarlo para pegar los candles wicks en los frascos de cristal?
