Whats this Fliuid Film stuff?

Yeah, but stay away from the smoke....wowie! Does it burn your eyes!

Hehe, I like the smell of the PB Blaster and the smoke from it

True, but the acetylene version is faster than natural gas, 2" bolt in under 30 seconds. I like that natural glow afterwards.

According to the MSDS sheet, that stuff is pretty harsh! Can cause possible nervous system damage JUST from the vapors! Assuming that your story is true, and the MEK is the same that you are talking about.... Did the guy survive?

Wow, I go looking for this to try a mix of atf and acetone for a axle nut I'm having trouble with and find this.

Yes that MEK. Yes, the guy did survive, it was like a instant gag reflex. The MEK hit his mouth and he spit it out. Very harsh stuff, and yes it is used as a part of the catlyst in Bondo fiberglass resin, but I think it's actually the peroxide in the catlyst that hardens the resin. I'm not sure about other brands. I used MEK all the time at the machine shop. It was a common thinner and cleaner for the aerospace paints I sprayed and a few of the epoxies. It would cause the rubber o-rings to swell and degrade in the guns, so I had to replace them frequently. It also worked really well for cleaneing the oils off of bare metal parts before painting. Also it's vapors are very flamable. Back when I smoked if I couldn't find my lighter at work, I'd squirt a little MEK in my torch striker and click it. The MEK would ignite and I'd light my cig.

it comes in spray bottles now..

My father-in-law swears by diesel fuel conditioner, says it will loosen 50years of rust over night. He restores old tractors.

I know that ATF has a lot of cleansers and rust inhibitors in it. It will also lubricate the part once it is broken loose and starts to move. I am wondering what Acetone does to the rust.

Are there any chemists that can tell us what happens when the Acetone hits the rust?

Ive used alot of these penetrating sprays and the one ive found to work best is Free All by federal process. Never used the 50/50 mix though...
