Forget the undercoat. You want the car oiled for around $100. The ladder displaces moisture. Google some of the places mentioned like Carwell, Krown to see which places are the closest even if it means a 2 hour drive. Also see below:

Yes the undercoat is a turn off. I'll do it myself again, and probably do a better job if I take my time.

Trav turned me on to Cor-Ban 22. I have a compressor and a gun to shoot it with. I just have to motivate myself. LOL

I've been doing it myself for 27 years. The motivation part is difficult. It's an exhausting physical job. But, as I've mentioned before, the effort gets paid back when you don't have to deal with rust issues later on.

I've had mechanics compliment my rutproofing job when buyers have the car inspected.

Picture the same level of detail, but for 1/5th the price and that's what you are getting from Krown.

Vehicle is hot-washed on a hoist with the entire underside rinsed off. A Salt Eliminator is applied. Then the entire underside is coated with the product including inside any frame rails, unitbody rails....etc.

Vehicle is lowered, panels and doors are drilled in discrete spots, wands are inserted and these places are all treated with the product.

Engine bay is treated, so is the hood.....etc.

There is no inspection fee. If they missed a spot, it will be touched-up at no charge.

You are supposed to come back once every 12 months for a re-application.

On a new vehicle, Krown has a lifetime rust free warranty as long as the vehicle is done within a year of purchase (IIRC).

What do you use? And how do you apply it? Thanks!
 
Fluid Film, Krown, RustCheck, and most other oil spray products are a type of lanolin based oil product. This is what is used by ocean going vessels and I believe the U.S. Navy uses the Fluid Film. It would seem to me that if the products are sufficient to use in the salt spray 24/7 of an ocean going ship it would be more than sufficient for auto protection. Most any of the oil sprays will protect.

I converted an old Sears paint sprayer for rustproofing. I had to make a custom tip where I could screw in some leftover brake line to use as a wand. The sprayer was designed to pressurize the container.

The rustproofing compound is cut with mineral spirits (as per instructions) so it's sprayable and can seep into cracks and rust. The mineral spirits flash off in a few days.

I tried oil once and it disappointed me. The oil dried off before winter was over, leaving my car with no protection.

Thanks, sounds like a good idea. What compound are you using?

Not sure about the others, but apparently Krown is not a Lanolin product.

"There is no paraffin, wax or lanolin in Krown."

I wonder if NAVSEA has a specific use of this stuff. It would make a mess of the nonskid, but I wonder if it may be used for helo tie downs. I would be interested to know where and how it is used, and if it is relevant to automotive applications.

Ive not yet used lanolin-based products, becaue the krown/carwell t-40 type inhibitor remains well enough.

Did you read the link I put up as to what and where the Fluid Film is/was used?

I agree about Krown/CarWell working as well as RustCheck. IIRC RustCheck was a branch off of Krown, some of management leaving and starting their own company.

Did not know about Krown not having lanolin in it, always thought it had similar properties as the others.

Krown T40 looks like nothing more than a petro product. See below:

The RustCheck Inhibitor also seems to be petro based but the RustCheck Coat & Protect is something else, not listed as petroleum based.

It was the other way around. Rust Check was first, with some of the management splitting and starting Krown.

WWII is entirely irrelevant compared to our current tank coatings (water compensated tanks) and use of F-76 and JP-5 fuels vice black oil. So if the claim is that the Navy uses it now, I want to know what the Naval Sea Systems Command (NAVSEA) approves its use for. That is my point. A cursory internet search implies something with helos.

Could that be why I used the terminalogy of "is/was"?

But then it might be relevant in that it protected against rust in the WW2 era, it surly will still protect today, at least in the area in which we are discussing, ie; automobiles and other vehicles used on todays roads in winter salt conditions.

Are they somewhat the same product?

I asked specifically WRT use in today's Navy... Re-read what I wrote. "I wonder if NAVSEA has a specific use of this stuff."

Could that be why I used the terminology of "if NAVSEA has"?

Im interested in current use. Not something that was used 60+ years ago. That was my question.

You do realize that the technology of rust inhibition has potentially advanced a little bit in 60 years, right? If a krown type product, or a corrosion-x type product or an Amsoil HDMP type product is better, then so be it. Thats why Im curious if current use, because if the Naval Sea Systems Command specs something better THESE DAYS, then I may be inclined to use that instead of 60 year old tech.

Maybe that is why Krown isnt lanolin based???
 
Pick, Pick, Pick, here we go again. Good Grief, let it lay!

Then maybe, just maybe the lanolin may be the best or maybe just slightly under the other, who knows? Some 60 year old technology is still good today and with little if any improvement.

I can say that the Fluid Film has protected against rust and stopped rust dead in its tracks in my experience.
 
Im asking the question. Notice how we have a lot of avitars of military people... I wonder if someone can answer the question.

Im not picking, Im asking the question.

American Society of Naval Engineers has a conference yearly called Mega-Rust, which is always keynoted by 2-star or higher Admirals.

Rust is a big deal.

Id love to know if FF and lanolin is a preferred approach.

Thats not a question for you, thats a question because were talking about rustproofing/undercoating and what is good to use. I use Krown and Carwell. If Lanolin is good for certain things, Im not opposed to using it also or in lieu of other stuff. I have no idea if Lanolin is truly in active DoD use. Id like to know, and if so, for what.
