Mark -
Permatex Anti-seize is the best thing ever invented. I think it's rated to
1,900 degrees. It never goes away and keeps the rust off, permanently. I
always use it on all bolts and nuts when assembling.
When I worked at The Geysers Geothermal Energy plant in N. California back
in 1985, we used the stuff to keep pipe bolts and nuts from corroding
together - the superheated steam we piped from a couple thousand feet down
has all sorts of sulfur, Hydrocloric, Sulfuric, and other nasty corrosive
acids which would reduce steel to rust in a couple of weeks. Whenever we
used that stuff, we NEVER had a problem with disassembly.
Smell is there for about 5 minutes after start-up, then dissappears.
