Reviews on this rust prevention product
 

Looking to see if anyone has any first hand experience with this stuff-

http://corrosionfree.com/automotive.htm

Theres a local body shop which is quoting me 150 bucks to spray this stuff under the car, engine compartment, inside door sills ect. With special emphasis on above the rear subframe and around it, behind the rear tires, and behind the front fenders at the bumper where they all rust.

Is this worth it?

In your case with what you've achieved in the past I would guess not - I expect you could probably do just as good a job (if not better if you remove the old rust first) with a can of POR15.

To put my comment in context:- I have no experience of this particular product. I'm wary of no effort cures - I think you always need to work at something like stopping (= delaying) rust.

this is a new, rust free car I found in a field. Every other car I have ever owned has been rusted, and now after buying this car, I find that I am quaking with fear that rust could start! :D

Its like the whole, the more money you have, the more concerned you are about losing it syndrome. I have more car this time, I don't want it to convert back to iron ore!

There are a few places where there is a tiny bit of rust that a dab of POR would eliminate which I intend to do, then the rest of it is a blank canvas.

I wanted to at least do something preemptively if it made sense, but I have been reading other posts about where some of the rust products actually increased the rust. I wonder if its worth it VS just washing the car biweekly all winter

EDIT- heres a pic of the new car-

Wow lush car - sorry to have read about your old car.

I can't add anymore other than saying that I did read here (on this forum) about some Canadian members talking about the sort of product you want up there... If I stumble across the thread again I'll post it here for you.

The non-hardening part of it I like. The problem with most anti-rust sealants is they form a hardened shell to isolate the metal from moisture/corrosives. In theory, this is fine. In real life they create "pockets" which when pierced (use of a floor jack, rocks flying up from the road, misc. roadway hazards) actually trap moisture and corrosives.

Do a search for Ziebart over on the Vintage forum. I posted some pics of a 250C I purchased which looked good at first glance.

Here's some pic's.

From the link, it doesn't look like this is designed for protecting bodies. It looks more like protection for moving parts. I'd talk to the manufacturer about uses.

Couldn't find a MSDS, so I can't give you a steer on what it is.

Key Phrase in the "Addvertisement"
 

"Apply every 18 months or annually as required."

drop back in the day when I lived in the rust belt, my dad would spray used oil on the undercarriage and in the wheel wells of his cars during the '70s and 80s before the winter sets in. I thought this was very effective because his cars didn't seem to rust.

sent an argumentative deal finding local friend over to the body shop to inquire about what guarantees you get with this product. Looks like none for 150 a season.

his logic made sense, but he body shop told him to piss off. :D

his question- "If I come here with a brand new car, and apply this product every season from then forward, if and when the car does develop rust, do you repair that free of charge or at a discounted rate since ive had years of rust proofing from your facility? What warranty do I get with this product? What assurances do I get in writing that you will actually decrease the chance of getting rust on my car, and what will you do for me if I DO get rust after all this expense?"

The answers to this were no, none, and nothing. Not surprising, but boy did the shop owner get irritated at these questions. :D

Still might do it anyway, but I think I will personally do a better job on my own than a body shop with a sprayer, at least I will fully coat known problem areas instead of the job I imagine they might do, a quick once over and out the door.

I've found that "Canadian" thread I was talking about:-

Hey Dropnosky,

I was referred to Rudy Schmidt to have 'Rust Check' performed by my mechanic, Jacobs Automotive. Dave Jacobs is a really conservative mechanic/MB owner and will not let me spend money frivolously.

'Rust Check' is essentially them spraying your car with a fish oil based lubricant. It needs to be applied every season but from what I hear is worthwhile. I also work with a guy who used to have the rights to 'Rust Check' here in Syracuse and he says its great!

Another rust prevention option I have heard good things about but have not experienced first hand is a device installed by Terry's Transmission in North Syracuse that send electronic pulses not allowing oxidation to occur. I have heard about cars in Hawaii using this due to the salt water and have a client who put this on his 10 year old Toyota daily driver and does not have a spot of rust. The advantage here is it costs about $300 but you keep it and can transfer to other vehicles.

OH! and Congrats on finding a rust free example!

P.S. Come to the MB club drive this weekend to Letchworth State Park ;)

Yeah, I know Dave too, he is not one to permit or recommend any gouging, I agree! Very honest guy.

I have some PORing to do first, what does Rudy Shmidt charge for their rust preventative spraying?

I had an F-150 once that had the electronic rust prevention gadget on it. Its hard to say with these things, but the truck WAS rust free, and spent its entire life on one of the islands off cape cod within a mile of the atlantic ocean, so maybe the electronic deal made it happen? Maybe not, there are a lot of negative reviews on the electronic method, like it not being a complete circuit-

I have not made up my mind, I have to do further research on that. It seems to me that theoretically, it could work the same way other items ground back to the battery on the automotive 12v system.

The club drive does sound like fun, unfortunately I will be out of town this weekend!

If you are into Volvos, saabs, or pugeots, you have to run down to where I got this car in Burdett. The guy has quite a collection or rare european cars, unfortunately less MBs, but also quite a few VWs.

I think Rudy Schmidt was going to charge me $150 to do my SEL so perhaps a little less on a 123.

Where is Burdett? I certainly appreciate all euro makes (mostly because they are unique and exotic relative to what we build/import Stateside). I would love to check this place out and bring a buddy along with me who is absolutely NUTS for each of the other marques you mentioned.

its Joseph P. Otatti used cars/ and or junkyard. He says he has something like 600 cars over an 80 acre piece of property. Not that many are visible, and some of them I think are at another yard. I did not walk that far into the property, but he was saying there is a dasher diesel wagon up there that needs some work, and some other stuff. Ill PM you the guys number and address.
If your friend likes vovlos, he'll like this guy, who races old volvo coupes in various leagues.

Burdett is south of seneca falls, like due west of ithaca on I think lake seneca. Next exit on 90 west of Auburn

Many people who have Citroens use WAXOYL on their non-galvanized steel. It's avaulable in Tractor Supply and other places. You can spray it in yopurself and it works very well, plus it flows and ocovers very well.

Put it this way: It's used in Britain, they swear by it and they have the worst humidity and rust problems I've ever seen, especially near the Atlantic coast.

I have used Waxoyl on my DS21. convertible which lived all its life in Arizona til I got it and still no rust after 8 years.
