Penetrating oil

Re: Penetrating oil

Tyler, a very dangerous combination. Acetone has a flash point of -20 F. Under NO circumstances should a flammable mixture such as this be used!

agree on the danger level.

Flammability
The most common hazard associated with acetone is its extreme flammability. It auto-ignitesflash point

Re: Penetrating oil

Today with everyone going green and worrying about polluting the atmosphere most all of our favorite brands have gone south.
If the Kroil is as good as the company claims it is then why isn't it readily available? Why is it the worlds best kept secret known only to a few.?
Here is the answer according to the hype on the can. Says not for retail sell. Industrial sales only. I looked for Kroil in McMaster Carr but couldn't find it. Meanwhile two cans should last me a long time.
Trick with penetrating oil is to leave it set for an hour or longer.
Went to a local auto store today called Auto Supermarket. They had PB blaster in 5 gallon containers. No 55 gallon jobs though for Farmer DW. JD

Re: Penetrating oil

I keep an 5 gallon pail of Aero Kroil in my shop. On smaller items I just immerse the entire part. Works great.

Re: Penetrating oil

I see Eastwood sells Kroil also. But it's another version called Sili-Kroil. Contains silicone and is big bucks. Eastwood has the sili-Kroil on ebay. Now it's getting confusing as various versions of Kroil are being offered.
One is Karo Kroil, Aero-Kroil(what I bought), Sil-Kroil, etc.

I am perfectly satisified with the Aero-Kroil. It cost about 14.95 plus shipping. JD

Maybe you could pour the Karo Kroil over your pancakes

Does it have any warnings about rubber parts John? I have an 885 Holley that I would like to soak in it before I attempt to tear it down. The governor diaphragm is not available in repro and I do not want to distroy it.

Re: Penetrating oil

Eastwood also advertises Kroil if you have trouble finding it.

Re: Penetrating oil

Just but it direct from Kano Labs in Tennessee. They are always running some sort of special.

My 2 emergency brake adjuster nuts were one large blob of rust the first time I went under there to do an adjustment. A week of daily Kroil applications and the nuts broke loose without a squeak and I am still using them both today. But, although I still swear by Kroil, I have to admit that Corrosion-X Aviation is slightly better. Slightly is not nearly 2 1/2 times better though. Kroil used to be $25/gal ($40 now) and Corrosion-X Aviation has been $100/gal for as long as I have been aware of it. The Navy did some extensive testing of this class of corrosion inhibitors and the Corrosion-X Aviation was at the top of the pack of about 20. That was mainly for corrosion resistance and not penetrating properties though. I find it at least equal to Kroil as a penetrating fluid.

I'll use PB Blaster or Liquid Wrench in an emergency. The only thing that WD-40 is good for is burning things for ill-advised entertainment purposes.

"If the Kroil is as good as the company claims it is then why isn't it readily available? Why is it the worlds best kept secret known only to a few?"

I can't speak to the marketing rationale for this mfgr, but it's NOT uncommon for some to restrict their distribution channels. Consider the BG line of products that don't exist on the shelves at WalMart and are only available through certain 'select' automotive retail outlets...

There are some who believe (right or wrong) that selective distribution is in their best interests. Plus, I too use Aero Kroil and LOVE it. But, I purchase it by going direct...

Re: Penetrating oil

Since I got the Aero Kroil this past week I have been giving my ignition switch assembly in my Model "A" (not even close to any Corvette) a small squirt or two.
Really impresses me. My son and I were just out in the garage and I showed him how good the switch is working now. He said Wow. What an improvement.
Wonder how its going to help remove rusty poc fittings from aluminum base plates-intakes. That will be the true test.

Re: Penetrating oil

John, that's where I had the best luck with CRC "Freeze Off" was getting the studs and POC's out of a base plate. Kroil oil did some but not all. After applying Freeze Off 10-12 over 30 minutes - they almost came out by hand. Works best on dissimilar metals. Let us know how Kroil works for you on the base plates. See ya at Carlisle. Gary....

Re: Penetrating oil

About ten years or so ago I received a case of "new" penetrating oil, recall name was "break away" or something like that. It was the best rust nut/bolt stuff I'd ever tried. After I used up the 12 small aerosol spray cans I ordered some. It wasn't the same stuff. Didn't work any better than WD40. Originally, their formulation was from mil spec tank barrel cleaner, but then the EPA got after them and they couldn't sell it to the public any more until the formulation was changed or so the company told me...

Gary you were thinking of "Break Free CLP" we still use it on all our large bore guns on board Coast Guard cutters. I used it to swab the bores of some M4s and a few personal weapons, its does a number on fouling and powder residue. Supposedly the federal stock system still has the good stuff.

[Gary C.]

Re: Penetrating oil

Todd, that's it. What I bought at hardware store was crap compared to the demo case. See gun stores stock CLP. Will have to give that version a try. The mil spec stuff I had would literally dissolve rust. Have you tried any of your barrel cleaner on rusty bolts? Just curious. Wonder if the website product listed as "civil" is the same as the product listed for "military"? Thanks for the update and for your service. Gary....

Re: Penetrating oil

We all have our favorite penetrating oil we swear by.
Although this is supposed to be a Corvette DB allow me to cheat and discuss my restored 28 Ford Model A with a 4 bangor.
The Model A has an electrolock popout igntion switch that was frozen and the key wouldn't turn. That's what happens when you set the collector cars in the corner with a car cover and don't look at them for 10 years or so.

Anyhow I tried various penetrating oils, graphite, etc on the switch assembly and none really did the job. I thought I was in for a major project and expense.

Two of our members, Dave Cardina and Don Baker, suggested that I try "Aero kroil". The Oil That Creeps. Orange label on the can has many claims. One of them says.
"Loosens the toughest stuck together metal parts or your money back".

Tonight I sprayed the switch assembly in and out with Aero kroil and let it sit for about 1-1/2 hrs. Guess what. Works really good now. I am impressed.

The Aero kroil is not cheap though but well worth it. Write Jesco Sales at
JescoWL@gmail.com
Dee & Kenny Cochran. I dealt with them on ebay and the service was outstanding. Nice people to do business with. Or call 337-433-3145.

John,

Been using it for years. Good stuff!!!!!!

BTW What are you doing working on a Model A anyway?

I just about mave my "30 Tudor up and running. I have had the chassis all finished for about 4 years now but have been dragging my feet on the paint. But now it is about ready for final assembly.

Take care,

Chris
