Best lubricant for unsticking stuck bolts?
 

Planning a weekend long lift install soon, and would like to know the best lubricant to squirt on the various bolts in the event they're stuck from the factory. It seems like the most common problem when people work underneath Jeeps is discovering that various bits are stuck and can't be undone. I've got 13 parts to install (therefore at least 26 bolts). There are bound to be problems.

If you've got the name of a specific product, that would be extra helpful. Thanks, all. :beer:

I have had good luck with PB Blaster...

PB Blaster will get anything unstuck

Heat.
Oxy acetylene, or even a butane torch can help

PB Blaster works the best. Spray the nut side the night before so it can penetrate. It uses catalytic action to draw itself into the threads so give it time to work. Don't use a torch on any bolts you are planning to reuse since it will take the temper out making them weaker.

Definitely PB Blaster, and a torch if they still wont budge. You should consider spraying them all and letting them soak overnight starting a few days before you start work if you want to be really effective, they should come out like butter afterward.

Mouse milk

REALLY!!!!!

Its an aeronautical product.

AeroKroil.

Absolutely amazing. After you're sold on it, impress your buddies that think WD-40 is a penetrating oil.

Screw loose, a good set of metric sockets, and a BFH

PB Blaster has NEVER failed me! I have used it on all kinds of vehicles....even some that were almost 20 years old so your JK shouldn't be anywhere close to the rust on those!
