oh yea, that is good stuff. I have used it at work and home and it works quite well.

I'm in the lighting repair business --shopping center and such pole lights If all goes well we only need to service a fixture every 3-5 yrs and have found a old electrician wire lube (slip stick) made from bees wax to work remarkably well for getting the screws loose after going thru numerous heating and cooling cycles . Boss asked me yrs ago what the hell I was doing with it all --told him and he tried it on his boat found it worked better than anti seize on every thing from the prop shaft up! I think 3m is now making a product know as well

the heat seams to cause the wax to wick up the bolt threads

The problem we had was that virtually any organic material we used as an antigallant would turn to carbon at 1200-1400F and become gallant . . . a pretty effective thread locker! The results are similar to the aluminum oxide that forms from galvanic action around steel bolts in an aluminum outboard! Grease or Tef-Gel works by insulating the dissimilar metals to prevent galvanic action and works well if it doesn't get too hot. The Kroil seemed to penetrate on a microscopic level. A colleague who had a side business overhauling turbochargers found that using Kroil was the only way he could get them apart, and he got Pratt to start using it. The use of heat and cryogenic liquid nitrogen also created enough relative motion between parts to help it work even better.

I agree. Kroil has no equal. We used it on a turbine powered boat. Things get hot and salty and generally stuck on a boat with gas turbines.

Awesome guys ! Thx. I'm going to find me some Kroil or order it because ' an ounce of prevention is worth a pound of cure ... '

Right now Kano labs is running a 2 for 1 deal. Looks pretty good.
