Best Penetrating Oil

[pbrown]

I need to deal with some stuck exhaust bolts on one of my non-Falcon cars. Who is making the best penetrating oil these days?

I've had good luck with freeze off, pb blaster, and deep creep.

Wd40 has some new specialist series that I wouldn't mind trying.

There is another brand deeze nutz or something like that I wouldn't mind getting just for the name.


Spray and let soak.. tap with hammer spray some more. Usually works for me

I'm a big fan of that Deep Creep by Sea Foam. Maybe it's just the bubbling action but it seems to really get absorbed into the cracks and crevices.

I used Kroil for ever and never broke a bolt, but last time I went to pick up a can at Tacoma Screw (the rusty screw replacement experts) they had another brand they suggested I try. So far so good with it as well, though I can't recall the name. It was less expensive than Kroil too.

I use Free-All and PB Blatser booth do well.

Rusty bolts on a non-Falcon? I say it's time to trade in the entire car.

If you get in a pinch and have the room to get in there, let me know BEFORE it breaks... I can sneak over this weekend with my portable Oxy/Axetylene with the smallest tip. You have lent me your welding machine so many times I'd like to try and return the favor.

You got me confused with a certain powder coater. :o

I'm going to try Kano Kroil in a spray.

Cant go wrong with kroil

LPS 1 or 2, best stuff ever.

it will take those non working hood hinges and a few spritz of it and your hood will shut like brand new. it also works for bolts:)

The Kroil did the trick for me. I had to remove several exhaust bolts on the Saab.

Has always worked for me as well. Bought a gallon of it 20 years ago before doing a full frame-off on my '56 Panel. Worked wonders. Could have got by with a pint, though I have since used all but a pint of it up.

FWIW, it doesn't like sitting in pump oil cans for long. Seems to almost reverse the anti-corrosion process after a while and the pump cans began to corrode inside and stop squirting. Some kind of scale built up. Using the tin-can bottom oilers solved that. Aerosol cans seem to last well too, but at the time I started using it they either didn't offer it in spray cans - or the cost didn't make sense. Too long ago to remember which...
