Would this work to glue it back in?** A: Be careful of sealant giving off toxic fumes the first few times you use it. Try heating up the oven 2-3 times before actually placing food inside that could absorb the toxic off-gasses. **Q: Would this be a good product for sealing a crack in a dishwasher liner?** A: Yes- I did this, along with filling in a gap on the dishwasher door gasket (which was ultimately replaced). Worked great! Be sure to clean the surface and rough it up a little (a bit of sandpaper, then clean the sandpaper dust off before application of the RTV). Used it a few years ago- is still sealed; all is well. **Q: Can I use it to glue shower mirror to tile in my shower** A: I wouldn't use it for that purpose myself. I qouls suggest an industrial caulking-type adhesive such as Loctite or Tough As Nails. **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. ## Frequently Bought Together - J-B Weld 31319 Black RTV Silicone Sealant and Adhesive - 3 oz. - Permatex 81158 Black Silicone Adhesive Sealant, 3 oz.
