Have a Question? See What Others Asked

Does the stick ever dry out? What is the longest you have had it open and it still works as expected for you?
INeed to remove the bolt, can you do it with tools? Liquid says yes, reviewers say stick is permanent. Can't be permanent for my purpose .
Has anyone used this with macbook screws? i'm hoping it provides similar holding power to oem screws, mine have been wiggling out a lot over time.
Is there a max temperature for storage? Basically will it melt in my Florida garage?

Building 3D printers? Voron builder dream!

If you build Vorons or 3D printers, this stuff is so good. It's not ideal to get loctite on the ABS/ASA plastic as it reacts chemically and breaks down the plastic, but with this stuff being thicker than even gel you can be confident it doesn't get where you don't want it.Use this for your 3D printer metal on metal connections.

Works great! Highly recommended!

I bought this because I needed something to carry in my small tool bag while riding motorcycles. The first trip, I had some bolts on my hand guards that were trying to walk themselves out, and were being a constant issues. I slathered the bolt up and stuck it back it, tightened it down, no more issues for the next two days of riding! This stuff is super handy, much easier to work with than the liquid stuff. I know I put blue locktite on those same bolts before I left, but apparently, it wasn't enough. This will stay in my little tool pouch that I always care riding.
