[Chrysler300] Rust buster

["Richard Barber" <c300@xxxxxxx>]

I have had very good luck with Kroil but the stuff is hard to find.  I
bought mine direct from the manufacturer at:  http://www.kanolabs.com/
Breakout torque is important but ability to penetrate may be even more
important.  E-mail below was from Paul Holmgren.

It is easy to booger up the screw slots on small screws--be sure to use a
screwdriver that will fill the slot and maintain good pressure on the
handle.  A little heat might help but be careful you don't set off a fire
bomb from the gasoline or penetrating oil.

C-300'ly,
Rich Barber

Some of you might appreciate this. Machinist's Workshop magazine
tested penetrants for break out torque on rusted nuts.

They are below, as forwarded by an ex-student and professional
machinist, Bud Baker.

They arranged a subjective test of all the popular penetrants
with the control being the torque required to remove the nut from
a "scientifically rusted" environment.

*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

The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic
transmission fluid and acetone. Note the "home brew" was better
than any commercial product in this one particular test.
Our local machinist group mixed up a batch and we all now use
it with equally good results.
Note also that "Liquid Wrench" is about as good as "Kroil" for
about 20% of the price.

Some time back someone had a formula for loosening rusty bolts. I 
thought I saved it but....  I have screws in some carbs that are VERY 
hard to loosen.
 Does any one have it and can send it again as I am probably not the 
only one that could use this info.
 Thanks,
 Jim McGowan
