Must have product for small screws and moving parts that you dont want to lose. Especially useful with firearms for installing sights and other items that need the small screws and what not retained. It is extremely useful and definitely worth the price. It is easy to apply with the dripper style tube. Does not take much especially of the red so this tube should last quite a bit for most people as I bought a tube years ago, use it quite often and still have some left that will last me a long while

This is a must have to secure bolts in place. It may seem like small quantity for the price, but it goes a long way. Just use a little, don't put too much. Dry time is fast. I use it on my motorcycles, most recently on a sprocket bolt. Ride with confidence. Highly recommend.

Perfect !
