For those of you who have never heard of it: I was turned onto Aerokroil by a friend who works at NASA and used this stuff at work. When I first bought my Bronco, I had a sparkplug that simply could not be loosened. I applied Kroil to it and after letting it sit overnight(24hrs is best to soak hard-to-loosen parts), I could turn the plug with my fingers! I've used it ever since and found that it works great. It's more expensive than WD-40(12.95) but is worth the price. I found this site that has it and does not charge shipping: http://www.storesonline.com/site/598452/product/AeroKroil

What a line :shocked
Use on the space shuttle do they?

:thumbup You know that space has got to tighten stuff up a lot. The stuff works great though.

as the janitor, sometimes he needs to bust loose that jammed toilet float.

never heard of it, but the Air Forces motto, at least my shops cause we do alot of pulling parts is, If it wont come off get a hammer. If it still wont come off, get a bigger hammer. or use the 1/2" air impact. Seriously we do that. but i just might have to give that a shot, but that prolube stuff that we got works good too

i agree

I was turned on to that stuff by a motorcycle magazine, and I've got to say that it is the best penetrating lube I've ever used. The spray can version is called Aerokroil, and it is also available in a 3-in-1 oil type can, but they just call it Kroil in that package. I usually use the Kroil, but it's the same thing. Great stuff.

If it wont come off get a hammer. If it still wont come off, get a bigger hammer...

thats why LOX buildup/vent valves always leak when servicing. thanks a lot.

If the hammer doesn't work, just call machine shop. That's what they're there for anyway right?

I hope it works as well as my space pen did. It would write upside down and everything
