  • This really works well.
Size: 3 Ounce
So this was a longshot. I have a hair dryer with a diffuser. Every time I use it the diffuser goes flying off. It's hot where it clips on. So I tried a bead of this glue and the diffuser is now permanently glued to the hair dryer and will not come off. It was the PERFECT glue for this application. It would be good for anywhere you need glue that gets hot -- like a stove gasket. Great product. ... show more

The rubber seals on my car windows were coming loose. After applying this adhesive and exposing them to high temperatures in the sun, they haven't come loose again.

  • Works for me.
Size: 3OZ 2 Pack
I use this for mycology lids, to ensure the injection ports stay sealed and in place. It has not failed me yet. I recommend filling a syringe for use on tight/small areas and putting a luerlock cap on when not in use. It does what it says on the package.
