Amazon took way too long to ship, when I placed my ordered it said that it was in stock! So why does it take near a month to receive it?Besides waiting forever the product works well.

It works just like its supposed to its strong enough to hold but also removable later on when you need to get it back apart. If you are looking for a permanent hold you should get red Loctite, that is what it's actually called and not what the color of the packaging is. You just apply it to the threads and then tighten it up and it will hold your screws or nuts in place from vibrations or movement until you need to get it off. When you do need to get it back apart you can still break the bond with force from tools. This is a good price for a decent amount.

One of the best products around if you want to keep your RC car parts from flying off at 50 mph. My only issue with the product is that it has very thin viscosity and spills out rather than drops out so a lot gets wasted. This is due to the squeeze container it comes in. The container is thick material so when you use it, don't squeeze, just let it drop by gravity and you'll have less waste.

What’s to say? When you need thread locker; you buy locktite. Works every time.

Colle correspondant exactement au descriptif. Elle n 'a pas coulé autour si on prend soin de mettre juste ce qu'il faut en tenant compte que cela peut déborder en appuyant pour fixer.
