Penetrating Oils

   An ion-activated penetrating oil which stops rust, and lubricates and frees rusted parts. It can also be used in assembly applications. When bonded to metal, it forms a protective coating and lubricating surface which is enhanced by other lubricants and corrosion inhibitors.

Part No. 4383
  Net Wt. 15.75 oz. (446 g)
  Volume 19.53 fl. oz. (578 mL)
  Net Wt. 3 oz. (85 g)
  Volume 3.69 fl. oz. (109 mL)

Just after many years of using this stuff on old rusty Winnebago parts, wanted to tell you guys to check this stuff out. It is one of the few that really does loosen old rusty parts. Here's a link to find out where to get it.

A study published by Machinist's Workshop magazine in their April 2007 issue looked at different penetrating oils to see which one did the best job of removing a rusted bolt by measuring the pounds of torque required to loosen the bolt once treated.
 Penetrating oil ......... Average load
 None ....................... 516 pounds
 WD-40 .................... 238 pounds
 PB Blaster ............... 214 pounds
 Liquid Wrench ......... 127 pounds
 Kano Kroil .............. 106 pounds
 ATF-Acetone mix.......53 pounds

But than y'all could try Mouse Milk Penetrating Oil..

I recently picked up a two pack of WD40 with their penetrant at HomeDepot. So far anything I have used the penetrant on has litterally freed right up right away with my hands. Although the only thing it didn't work on was my original pressure gauge manual fill spout for the water system, which after a little careful inspection appears to be JB welded on.  ;) Seems to be great stuff, and easy to find, but the cap that converts from big area to focus area with the long hose isn't designed very well.
