## Questions & Answers

**Q: My portable convection oven (heats to 500 degrees) glass door fell out of the metal bracket. 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.
