Peanut oil exhaust anti rust treatment

[Merian]

Let me clear up a few things here.

Chemists have actually done a few studies on this, and there are two mechanisms at work.

1. polymerization of the long chain component of the oil - which will add a thin layer on top of the metal and will (likely) be chemically bonded to it
2. carbonization - which will affect the surface layer of the metal

Linseed oil will do the best job. Food grade linseed oil is called flaxseed oil. If you are worried about flames (from the very thin layer you will put on), then peanut oil will work also.

Not all oils will work. The type of oil you want is one that polymerizes, often called "drying oils," tho they don't really dry out, but instead polymerize.

The efficacy of this treatment will be limited. As pointed out above, the inside will not benefit; moreover, areas that do not get above the smoke point will not get carbonization, only polymerization benefits.

If you want a lasting exhaust system then get high-grade stainless steel. You can do better with inconel, and it will go well with your carbon fiber monocoque and hydrogen fuel cell drive system.

I tried this one one of my coats that made a few drips during the application....wiping the coated pipe after the brushing on with a clean rag, than firing the engine to heat it.

We are having the first of three days of rain here in NY.
I will be driving the coated van.
Tomorrow sounds like heavy rain.
I will post some more pictures after it has seen some road spray.

Dear God, what have I wrought?!!! When I first recommended something as mundane as coating an exhaust system with peanut oil, I never imagined that a dozen years later it would generate 9 pages of consideration on theSamba.

Look, it's cheap (especially if spent p-nut oil is used), it'easy and it's effective. Moreover, Mike Popovich, the one and only Tube Guru from Johnstown, PA, tested it and put his stamp of approval on it long before many of these recent devotees could scrawl Vanagon with their jumbo Crayolas.

So, stop looking at the purty pictures and just do it to it.

Richie,

I think perhaps rather than making the announcement on this simple to use exhaust sytem extender, you should have bottled used turkey frying peanut oil years ago and made a bundle.

The issue here is it's way too simple of a concept for folks to follow, and a lot of them choose to deviate from the simplicity of the cure.

I paid attention, I slid it into the grey matter rol-a-dex, because it worked out well for me, back when I had my first Vanagon, which had a questionable exhaust system.
I oiled it up, it lasted for the 5 year duration of me owning it.

I salute TheTube Guru, and the Chef Of The Future ( you ) for bringing this concoction to my attention.

Bravo.

"Vanagon Exhaust System Extender"
In pink pint bottles, with a hint of turkey bouquet would have made you a million.

You really missed the boat on this one--nobody would have figured this mighty fine cures recipe out.
Too simple.

Up until this Peanut Oil Marathon, I know of only 4 folks who have used the treatment.
Mike, Pinky, You,& Me (there might have been a sprinkling of the Vanagon.com circus that may have-don't remember)

I'm happy to see some of the other folks here give it a try.
They'll be happy they did, and so will their exhaust systems.

TK, I bet by this time next year, Lucas will have a propriety formula of a first pressing Organic Peanut Oil packaged in a fancy bottle and sold for the incredible low price of $19.99 shipping included.

Your right Bobby--

He doesn't miss too much, and probably has some Amigo's down in Tijuana cranking the magic elixir out as we speak--

I'm having a hard time figuring out what people don't get.

This is a brilliant idea, and anyone who has used a well seasoned cast iron pan will understand at least the basic idea. I don't have pics but I went ahead and did it to the exhaust of my 92' Town & Country, and after the 2nd coat and heat it looks pretty great. WAY better than it did before. (yes I realize it's not a VW Vanagon, but I don't have one of those yet and wanted to give it a go.)

If you think the peanut oil is a difficult miracle in a bottle to digest, you should know how long I was telling folks with faded pop tops to simply wipe a coat or two of Penetrol onto their chalked out fiberglass for a brand new appearance.

I started mentioning that easy treatment back in Vanagon.com play days too.

Nope, your nuts, buffing & waxing is the only way.
And believe it or not there are some real muley folks here still doing it the hard way.

I should have bottled TK's Fiberglass Rejuvenation Syrup up way back when, along with Richie's exhaust system elixir.

Would have made a bunch.

Forget telling folks how easy stuff works, Nupe.
Charge them $29.95 a pint & it'll be the best stuff since Miracle Whip.

It is already NLA Richie.
Out in the Kingdom of Kumquats.

The surfs out there have to smuggle oil based Penetrol in, or buy it via the black market.

Start warehousing it.

Well, FWIW, Ive been putting the peanut oil on ever since I first learned about it. I apply it every 6 months or so, sometimes sooner simply because I dig the way it smells. I use an old squirt bottle to spray it on...I can definitely say, without conviction, that it is slowing down the rust. A buddy of mine thinks I'm crazy for using it. But I haven't had to replace exhaust parts for a few years now either...
