Review: perfect size and quality - perfect size and quality
Review: Works great - At first i used it with the nozzle but its hard to squish it out so I had to cut it from the second circle to make the hole bigger which worked, please do not force it through the smallest hole since Ive seen some comments complaining that it bursted open and made a mess. I would recommend you remove the nozzle when you are almost done and clean it properly by passing tissue through it, using some of that product leftover. While this might be messy and a bit wasteful it will prevent both the tube and the nozzle from drying up since the nozzle doesnt have a seal. Now i use it without without nozzle and it still works nice for areas that dont require precise application or tight areas and its an amazing adhesive, it says it dries in 1h but id recommend leaving it at least half a day, do the work at night and leave it overnight maybe. Ive used it to glue some shelfs in the kitchen and put spices and sauces which can be quite heavy, left milk and other heavy items to test the durability and its been 3 weeks holding all that weight, also used the glue to seal corners in the bathroom and its completely waterproof once dry. The next time u open the tube there will be a dried up crust on the top, if u squeeze a bit it should come out, i didnt throw it away and actually placed it back once im done using the product and this actually works as a second seal that prevents another dry crust. Overall amazing product.

## 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.
