I got this off a Tractor forum. Farmer may know??
Anyway, has anyone here heard of or tried this?

"anyhow we build industrial equpiment and lots of it is S.S. and yes it will seize as a small nick is all it takes, those bulk bins are great for having the stuff all piled up and one scratch will end up stopping the nut from bottoming out. one easy fix is to use a tap & die to clean up the threads before you attempt to install them... the other thing is to install them SLOWLY. Oil or anti size don't seem to make much differance if it wants to sieze it will. what seems to help is a good coating of "milk of magnisia" the cheap phillups stuff you take for upset stomach, (works great for header bolts too! best stuff for them made!) the chaulky ness of it forms a slight barrier and will help removal too.

When I was in military it was the ONLY approved thread sealer for after burners on the B1 at the time. It seals and makes removal easier and the stuff wont react. as it dries out the magnisum is left and it will bite into the fastner holding it in-place untill you start to turn it, then as the bolt turns a bit the stuff goes back into a poweder form and acts like a lubercant againe making it come right out the rest of the way.

I have all my exhaust header bolts on with it and have removed them lafterwards with out a bad problem one. last tiem I took them off they were on for almost 5 years. not a one loose or seized..."

Haven’t tried it but very interesting.

MOM is made with magnesium. It would work as an anti-seize (especially in a magnesium part that might be subject to corrosion with a metallic anti-seize based on a more noble metal) but I prefer Permatex 80078.

Would not recommend the permetex for an upset stomach though.

And the 3M/BoatLife poly sealers work too!

I use nickel-based Neversieze and have found that it does stop ss galling, as well as make it possible to remove exhaust manifold nuts and bolts several years later. Milk of Magnesia may also work, I have no experience.
