Doc	Re: Rusty Nuts... I think Gus means stuff named "Kroil". It's an industrial penetrant from (I hope this is right) Kano Laboratories. It comes in a cans with an orange label, and is only available in gallon containers or case quantities of spray cans. It does work much better than any consumer grade stuff I've tried, including WD40, CRC, and Liquid Wrench. They also offer a premium grade, called SiliKroil, which has silicone added to regular Kroil. It creeps in anywhere. Actually, automotive transmission fluid (that red oil) is a pretty good penetrating oil. There is another juice available at auto parts stores, called PB Blaster. This stuff works great (I use it on stubborn shock absorber nuts), but comes out of the can in a forceful jet. Better to spray a little in a small container and transfer it with a small diameter drink mixing straw using capillary action, by dipping one end of the straw, then capping the other tip with your finger and letting off when the straw is positioned over the rusty joint. One thing you might try is remove as much rust as possible by careful mechanical means first. Use a tiny wire brush, the ones that are about the size of a toothbrush. With all the large oxide flakes removed, the penetrating oil can get right down to the actual joint. Don't bugger up the nut with the wrong tool, like pliers. Use a proper socket, either a nutdriver or a 1/4" drive ratchet set. Also, these penetrants take time to flow in and dissolve rust. Wait a day and then go back with the wrench.
