The best protection out there for dissimilar metals
Expensive but the best. After removing and snapping multiple stainless steel bolts from aluminum hardware I’ve swore NOT to be the guy that does that to the next owner so I apply this liberally to every bolt I install.

Smear it on
It’s tef-gel…I put this stuff in every stainless installation I have. Awesome stuff and I’d aware by it! If you have corrosion concerns, you need this.

Got dissimilar metals? Buy this!
Used for years with stainless, aluminum, & other alloyed metal interfaces, especially when water is involved - best stuff ever! Even used it to protect banana plugs from the acid on an SnLayer Tester.

A little goes a long way
Great stuff for preventing stuck bolts. Tiny tiny container, but it goes a long way. Pro-tip, dont use the included applicator, use a toothpick to apply to threads. It really doesnt take much

Time will tell
Only time will tell if this stuff works. Keep a paper towel handy when you use. I put this on every stainless steel screw I use when installing accessories on my aluminum boat.

Work well, but a sticky mess.
I have not had any issues with galling since using this. I hope that it's anti galvanic action works as advertised as it will take years to know fro sure, but I have used it on stainless screws in aluminum. The one thing I don't like about it is that it is a crazy sticky, gooey mess! Once you open the can and use the brush, it seems to get everywhere and the stuff is really sticky. It also does not wipe up easy. You have to get it off with solvent. The best way I've found to store it is in a zip lock bag because the outside of the can will end up covered with it and then there is the brush...

Best in the west
Used against salt. Other than like red n tacky machine grease, this is the only stuff that really can prevent corrosion. I use it instead of antiseize on our undersea equipment. It is expensive, but, it doesn't take much for it to work so it lasts a long time (this big cup) and it actually works.

Couldn't live without it!
This stuff is absolutely great and not like that other gray stuff that gets everywhere once you open the bottle. I use it on sparkplugs, bolts, nuts, etc., and anywhere I want things not to seize nor rust. NOTE: be aware that torque values are usually given for dry, clean threads and might be different when using anti-seize compounds.

Ottimo! Consegna puntuale, contenitore integro. Attendibilità 100%! Lo uso per anti corrosivo in ambito nautico.

This works but you need to get to grips with the consistency as its like toothpaste with superglue in it.
