Everybody knows the oven is the best bet because you cannot put metal in a microwave silly.

 

Use PB blaster that stuff is the best. I was trying to take off my strut bolts on one of my old cars and I first tried liquid wrench and it didnt do any thing so I went to the auto parts store and seen PB and I was scepical untill I used it and now it is the only lube I will use.

 

yea i too love the PB i had used it in autos class and saw how good it worked and now i won't try a rusty bolt without a couple squirts of PB. the only problem is the odor that stays around for hours.

 

Yeah, but the odor is the best part of the PB blaster!.

 

Yes, the PB Blaster is amazing. It is all I buy now. I don't think liquid wrench ever did anything for me besides make stuff oily.

 

I used to use this stuff called LPS they had different numbers for different uses. 1 was a silicone, 2 was like WD40, and 3 was the best penetrant and rust inhibitor in the world. Spray it on, count to 10 hit it once with a BFH and then turn the nut or bolt and it would come right out.

 

The best rust penetrant I ever used was at a dodge dealership, made for Mopar. I haven't been able to find anything even close, i think it was pretty much just graphite in naptha.

 

i have heard of using diesel fuel in the cylinders to free a stuck motor, dont know if it would work, never had to deal with that problem, p.b. blaster is some great stuff though, i beleive that stuff would work. had a clutch stick on a tug once that had been in some high water, had to loosen all the pressure plate bolts (you could access them with the inspection plate removed) and use a bottle jack agaisnt the ring gear, got it done but took a while.
