As advertised - since it's an anti-corrosive, only time will tell how well it works. But it seems to be doing the job.

I used the Tef-Gel on stainless steel bolts on my aluminum boat trailer to create of buffer between the dissimilar metals. It is very easy to work with and created a watertight seal.

Whenever you have dissimilar metals like SS machine screws into an aluminum mast. Makes the screws or bolts go in easy so that they are easy to remove when necessary.

Any time I use fasteners into a metal I use this. Great for preventing the corrosion from stainless fasteners through Harken aluminum parts.

TefGel is the real deal. Don't use any "pretenders". For preventing dissimilar metal corrosion, corrosion in general and anti-seizing, it's the best. I've use it on every electrical connection I've made in the last 10 years and haven't had a corrosion-related failure yet. Great stuff.

I used tef gel on the packing in the stuffing box- buttered some in with gland nut backed oout, then hand tihtened til some pushed out the shaft...then 1/4 more turn- stuffing box performs well year after year- no annual adjustment needed...

This stuff works. It looks expensive but it only takes a thin film to make it stop the dissimilar metal corrosion. It takes a little work to get it off your hands and has the consistency of very sticky grease. It seems to a better than grease substitute for items in a harsh environment.
