WD-40 = Duct Tape.

Years ago it was Naval Jelly for serious stuff, not sure if it's even out anymore.

Must be nice to live in an area that doesnt use salt on the road.

If you would use a break bar/ cheater bar on some bolts I need to take off you would just snap the heads off.

Yeah it's one thing I really appreciate about So. California. :awe:

When I was on my first (Navy) ship, we used oil of wintergreen. Got it from the medical section (guess it's used as a topical muscle relaxer), and it was thin enough to creep through rust that Kroil wasn't having any luck with.

Goddamn, that is quite impressive.

I have 'Naval Jelly' in my shop (which is a REALLY awkward name...) but it's for dissolving rust, it doesn't really penetrate worth a damn because, well, it's a jelly not an oil or fluid.

I removed the lower shock mount bolts on my ~270k mile '99 Tacoma with a 3/8ths ratchet.

Soooo, when are you moving to Arizona?

yup, great for rust removal, not so great for penetrant.

Try to get an HDPE (high-density polyethylene) bottle, not PP (polypropylene) or another shittier plastic. HDPE, or just PE, stands up well to many, many chemicals.
I just checked some charts. HDPE and PP are fairly comparable, with some wins and losses for both.

What about mineral oil or even motor oil? Maybe take some of your motor oil, throw some acetone in there, and you can starting using it all over the chassis. Poetic.

I wish they would've made more test samples, though.

I've tried motor oil with acetone... would advise against it. Strongly. Does not penetrate well at all.

One of these years I'm going to try chassis oil spraying with heated oil + turtle wax... but that is not this year.
