Good thread lock
If you can get past the gooey consistency this stuff will save you so much money. For the size, and strength of this thread locker it's comparable to the best on the market

Great value!
I didn't realize how large a bottle this actually was until I received it. While it's possible that it's contents may go bad before I use it all, it did not cost anymore then much smaller quantities from other brands. I typically purchase a US made product when available, but my go-to threadlocker in it's comparable form was not US made like some of its other products. I won't pay more if a US vendor is simply buying an overseas product and marking it up; in that case I buy direct. It has a very nice nozzle that opens and seals to keep the product fresh. That's an important feature in a larger bottle like this. Additionally, this is actually closer to a gel than a runny liquid. Most vendors gel products are significantly more expensive, so that makes this an even better value.

Good alternative to loctite.
Used on many bolts after removing driveshafts, transmission and transfer case and rear main seal on 1999 F250 7.3L diesel with auto transmission. Its sort of gel like so doesn't just run off threads
