"The Great Rust-Off"

Interesting, only nissan crawler has ever mentioned weatherpruf here, available from Kano Labs.
WD-40 did better than products like Starrett M-1 and Kano Labs Prevox, which is surprising to me.
Has anyone used Kano Labs Weatherpruf? What type of 'film' is left behind after application and is it suitable for tools?

Yea, I'm wondering the same thing. Is there a film?
I would also like to see what happens if you left the WeatherPruf piece out longer to see how long before it rusted.
How about the lubrication properties?
Might have to get some.

I still have a gallon of Brownell's rust preventative. I haven't used any but in my mind it's the sh*t. It's used on guns in storage and to help prevent corrosion especially from handling. I can't recommend it as it is expensive but if you come across some at an estate sale or auction pick it up. If it's cheap! Well that may only apply to me.

Greetings,
WeatherPruf provides a clear soft coating that Kano claims will provide 1 year of corrosion protection.
Kano recommends mineral spirits to remove and clean up WeatherPruf.
Kerosene works just as well.
WeatherPruf is not oily and I doubt if it has lubrication benefits.
I have used WeatherPruf on milling machines and lathes that are within proximity of the salt air and fog from the San Francisco Bay.
WeatherPruf has also worked well on dies, cutters and tooling.
WeatherPruf has eliminated stubborn corrosion problems.
Unlike Cosmoline, WeatherPruf does not have to be removed before using the machine.
WeatherPruf does not interfere with the machine's mechanical motion and slowly disperses with contact with the machine lubricants, cutting fluids and coolant.
WeatherPruf is $11.00 for a 10 ounce spray can or $38.75 per gallon:

Ned - Big thanks for your test!
Also, big welcome to garage journal!
How 'thick' is the coating it leaves behind? Would you be able to notice it by looking at a black oxide impact socket?

Greetings,
Thanks for the welcome.
The WeatherPruf coating thickness is similar to the coating thickness of a coat of spray paint.
A black oxide socket would be noticeably coated with WeatherPruf as it would appear as though it had been painted with a semi-gloss clear coat.
The WeatherPruf coating is a soft non oily emulsion that will come off if it is abraided or subjected to alot of handling.
I simply respray the WeatherPruf as needed after operating machines or handling tooling.
The Great Rust Off was conducted as per the ISO 11474:1998 Accelerated Outdoor SCAB Test which is the same test used by NASA at locations in Florida to test space craft materials.
The test includes exposure to sun, wind, dew and salt spray.
I had never seen or heard of WeatherPruf before the Great Rust Off.
All of the products tested in the Great Rust Off were recommended for test by home shop machinists.
Before the Great Rust Off, I was using Mechanics brand silicon spray corrosion protectant which was good in most cases for 2 to 4 weeks.

Thanks again Ned, I think your test aways countless thread here on rust protection for tools.
I happen to have some Super Lube Synthetic Lube on had so I plan to start using that as rust preventative.l (I didn't know that it was effective on rust like you showed.)

Us Canadians use Rust Check as a rust preventative.It's something I never see mentioned when these discussions come up.Perhaps it's not as readily available south of the border.

Thanks, excellent link, I'm right in the middle of cleaning all my tools, and I mean cleaning. When I used to use them daily I kept them real nice but the last few years I haven't been keeping up. I was actually looking for Corrosion X, not anymore.
Any other tips for cleaning like what cleaners you use, etc? I've been using Simple Green for the covered handles, mineral spirits, steel wool for rust and then spraying them down with WD-40 and wiping them off.

Just goes to show - you can mix up any number of "new" elixers (and charge much more for them!) when there was nothing wrong with the old standby.... in this case 30 wt oil on a rag would apprear to be the best (performance, price, availability).
While I like the methodolgy used in Ned's testing - and I realize the saline is used to accelerate the corrossion process - as was said by Danglerb,
I'm in the middle of a 1 year test of two rust-proofing paint products (ZeroRust vs POR15) for another site. It's more of a "real-world" test, whereby a rusted tailgate was coated equally with the two products and left outside. Where I live, it will have been exposed to ALL weather conditions and some of the most extreme temperatures on ther planet.
Welcome to the forum Ned - we can use more minds like yours and OCG's!!

What would you guys reccomend for rust proofing a car? For places with road salt in winter and such. Is there anything out there you can spray all over the underside to protect it?

Greetings,
At the time, I performed the Great Rust Off corrosion test, I assumed that non detergent 30 WT oils were the same or very similar.
I selected the Chevron 30WT oil because it was conveniently available and because my father and others recommended testing 30 WT oil against the other high tech products.
However, Rob Hoffman, a member of the Smithy Machines group, has convinced me that the Chevron 30 WT oil is not like a typical 30WT oil due to its formulated additives.
What follows is an email from Rob in June of 2009 with his test results and photographs that should be definitely considered as the finish of your machine may be at stake:
Ned...
Please excuse me for sending this to you outside of your group as I did not want to start another thread on this topic. You may do with these results as your program dictates and with my permission to use however you see fit.
Test object...mild steel mower blade sanded bright and degreased with TSP. Completely dry and clean before test subjects were applied.
Test coatings: Nothing. Control area in center of blade.
BoShield T-9 Spray
Accell Brand 30 wt, ND motor oil (Walmart)
http://www.home-machine-shop.com/Rob_H_Test-1.JPG
The surface was exposed to rain, saltwater, sunlight and outdoor conditions for one week after a single (liberal) application of the test coatings. Test conditions included laying out on a dock, riding on the bow of my boat and being carried on the bumper of my truck for about 1000 miles. Care was taken not to touch or disturb the coatings other than the environmental exposure factors.
I think the results speak for themselves. The Motor oil was better than nothing, but not much better. The BoShield was not perfect, but easily out-performed the straight-graded mineral base Motor Oil.
http://www.home-machine-shop.com/ROB_H_Test-2.JPG
I'm thinking that the Chevron Oil you used in your test had their usual additive package in it, but they have not responded to my request for information regarding that...I did send them an email, but as yet they have not sent me anything.
The Accell Motor oil is a pure mineral oil according to it's published spec sheet which is available on line. It has no additive package at all. The additive packages in motor oil vary a lot, but most contain anti-corrosion chemicals that I suspect were more responsible for the results you obtained in your test that any inherent properties in the mineral oil base stock.
So, I would have to take issue with any flat statement (or test) that found that "any good `ole cheap 30 wt ND Motor Oil" (with no additive package) was the runner-up in any rust prevention contest while competing with specialized products designed to do that job. From my test, I'd say the Accell Motor Oil would be close to the bottom of your list, which leads me to suspect that the Chevron Oil you used also had some very effective chemical corrosion inhibitor additives in it that actually did the job...not the oil itself.
Best Regards...!!

Anything oily or waxy that clings!! There's a couple products available, but you could also use WD-40 or some such stuff, or - as per Neds rust off - spray 30 wt on it!!

After trying a bunch of different rust control products I stayed with Ballistol, a major plus for me is when used on guns it will not harm or soak into the wood, it also protects wood, leather ETC. I also dilute it with WATER as recommended by the manufacturer.

My shop solvent is K1 kerosene. Kerosene is used in the kerosene heater, in the parts cleaner, as a cutting fluid for brass, copper and aluminum, as a dielectric fluid in the EDM machine and as a charcoal fire starter in the BBQ.
Kerosene should be used in a well ventilated environment without sources of ignition and equipped with a fire extinguisher.
In over 50 years, my father and I have never had a shop fire due to kerosene.

For protecting the bottom etc of a car, nothing seems to have improved on Cosmolene.
I didn't notice, was anything special done to clean or prep the metal prior to applying the goop?
How about trying some type of car wax?

Well, I ordered some Weatherpruf myself. I can't keep rust off my damn drill press and dimple dies, and it's royally ******* me off. Even kroil won't do it. It works for a while, but after a week, the **** starts showing up again.
I'm going to wire brush the hell out of it, clean it really well with alcohol, then soak in weatherpruf. Hopefully that will do the trick.
