rust and penetrating oils

[23JDCA 808]

I had a window winder whose chromed brass knob was rusted to the steel pin. I soaked it in vinegar and worked it by hand for a day; freed right up.

Hunt up some CorrosionX if you can find it. It's military spec.

I'm intrigued by the gentle but effective nature of this Strongarm stuff. Has any body used it to remove gas tank rust ? if it has to be rubbed on, why couldn't a person put some Strongarm with steel shot in the tank, agitate by shaking and wa-la !?? i've never tried molasses, but i am really tempted to give it a whirl until i just did a brief study on Strongarm. i've always used 3% solution phosphoric acid until the past couple tanks when i switched to electrolysis and washing soda solution. I'm intrigued by the idea of trying Strongarm in my JD tanks since Strongarm is apparently a rust remover and inhibitor.... no flash rust.... ?!

I have had such poor results with Liquid Wrench that I now use what I have left as a cutting lubricate when machining or drilling steel. It works pretty good in that application. I have fair results with PB Blaster.
Whatever is used, it must be given time to soak and penetrate.

[Steve Swan]

i just bought a new case of Kroil, the first nozzle works fine.

the last case i bought probably 2-3 years ago, every nozzle was defective. A friend of mine bought a case at the same time; all his nozzles were defective too.

[Chris Haynes]

yep, my last case the nozzles were defective too.

All of mine have been troublefree.

[Steve Swan]

I did too, Chris!

But the last case of spray cans all have faulty nozzles, and customers brought them all back.
(And too late for me to complain to Kano....)

Now I have a lifetime supply in bottles with an eyedropper, and a wall display of the rest of the case.

Lesson: Buy it in the jug.

I stumbled on this thread while looking for information about 'Strongarm' after talking to the Strongarm guy at the Anamosa, IA swap meet last weekend. He's very passionate about his product. There were a couple of good comments about Strongarm, but mostly I enjoyed the razor blade discussion. The concept of putting a razor blade aside until you've dulled a couple more, and then reusing it and finding it sharper reminded me of how I handle my laundry on a long motorcycle trip. I always fold my dirty shirts neatly and put them back in my saddle bags because I find that, after about a week, my dirtiest shirt has somehow become my cleanest shirt. This phenomenon has been repeatable many times over.

Strange but true.

As for the Strongarm, I was am interested more in using it as a preservative than a penetrant. If anybody has experience with this I would be interested. Up to now I've been using Gibbs oil for preserving rusty metal, with fairly good results if it is reapplied every couple of years. I'm wondering if the Strongarm performs better, worse, or similar to the Gibbs.

Thanks.

Yes Tom, VpCI goes from crystal to film then sinks into the substrate and as it does this the anode and cathode charged inhibitor molecules prevent the electrolyte from contacting the metal.

The process reduces the corrosion rate 5 to 7 times.

VpCI was invented for the US Navy in the 40's, but over the last 2 decades, CORTEC found a way to use environmentally friendly amine carboxylate for the active compound that controls corrosion. Formulation was tweaked to be able to apply the VpCI to extruded films as well as other products from coatings, penetrating compounds, cutting fluids, oil process industry and other categories in the MRO business.

Tom- After I bought some Strong Arm Spray at the Davenport Meet a few years ago, I have always ordered it by phone. The number is on their website strongarmbrand.com. I believe it ships out of of Iowa. I'll drop some off to you next time I'm in your area.

Ric!

It flip-flops like a chameleon?
I still haven't found the CP-90, or Roger Brandstatter's "Strong Arm" locally.

My studies may have to wait until it isn't -7°F, and the 53+ inches of this winter's snowfall has subsided.

Dipping steel in brine sounds familar, though.

I have a relatively light beard myself, but....
Is this CORTEC VpCI like dry ice?

....Cotten

Tom, Cortec VpCI is a friendly salt, 5,000 time less lethal than table salt. The chemical name is amine carboxylate. The chemical has the ability to hold an anodic and cathodic charge and is chemelion like in application. Works as a crystal in it's non activated format. Because of the small charge held by the chemical, the chemical has a magnetic attraction to metals.

The chemilion part is if oxygen/moisture are introduced once bound to the metal, the chemical converts from crystal to film and then is absorbed into the metal substrate @ 90 nanometers whice surpasses travel of contaminants that cause corrosion or in the case of enriched electrolyres keeps the solution away from the substrate.

This in turn lowers the corrosion rate 5 to 7 times and in this case is enough to feel the difference when shaving with an aged blade.

i have used coke a cola to free up stuck hardware. it works good for steel studs or bolts that thread into aluminium.

[BoschZEV]

I make a distinction between "free" and "effective".

An important corollary to this is that there also is a distinction between expensive and effective. For no good reason I searched eBay for Rusteco and I got only one hit -- someone selling a qt. bottle of the stuff for $75(!). As I wrote earlier, the stuff has worked fine for my purposes, but no way is it worth $75.

Cory!

Please note that I used the term "quality" razors



....Cotten

I did note that you meant "quality" Cotten. I couldn't shave with a "BIC" if I tried. I'm forced to pay for the good stuff. After further reading this thread, perhaps their downfall is partially due to my method of caring for them.
