Love it
Mechanics gold, my loctite lipstick, you can get some mileage from that joke, does the job without all the shaking the old bottle that’s settled out, no mess, no worries about falling over. Lasts as or longer than the small bottles. Very convenient for awkward jobs.

So much easier to use than the bottle
I used this when reassembling pocket knives. The little screws get a tiny bit on the threads and the cap is popped back on. No more leaky bottle where I have to put a drop on something and then carefully dip the tiny screw into the wet and then not have it run everywhere. So much easier to use and control with the paste like consistency. Since I use so little the stick will probably expire before I ever use it but I will replace it with the same thing again. Wish I had known this existed years ago or whenever it was released.

LOC-TITE Blue Stick
Awesome quality item for many uses. Perfect for tiny screws when mounting a scope or when replacing screws on a knife.

Best formulation for a thread locker!
The best way to use thread locker. The soils stick allows for much more precise and co trolled application. Use a toothpick and place a small dab EXACTLY where you want it. No drips, no runs, no errors!

Wished I knew about this product sooner.
Better than nail polish, or other liquids so far. Easy to apply.

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.

Best way to buy loktite
The sticks last a very long time, and are much cleaner than the liquid. They will dry out after a while, so keep them in a plastic bag when you're not using em.

100% Recommend Excellent Product
I bought this product to use on very small screws for RC cars. So much easier to use than the liquid by miles. No drip, easy to apply the amount you need. Works just as well as the liquid, just be cognizant of temp. Too cold and it's a little lumpy in application. Otherwise, super easy to use. 100% recommend
