Krown do-it-yourself Rust Protection

Yes, it is available at Home Hardware but $55 for less than 4 litres? That is twice what I pay for Mobil 1 engine oil. Heresy!

Many years ago I enquired at a local krown shop about buying a 5 gal pail of the KrownT40 and the guy quoted me about $340. I had to bring in my own pail and he would fill it from his bulk tank. Needless to say I did not buy from him. I very much doubt he was paying more than $5/l when he gets his bulk tank filled up. Napa had a special on 4l jugs of rustproofing oil at the time and it was less than half the price of Krown, so I bought from Napa instead. Steviec has posted previously about Krown being a high Zinc oil but I still cannot stomach the price.

KrisZ turned me on to Monarch Oil in Kitchener, so now I buy from them. The dripless undercoating is less than $5/l. I sprayed it last fall on my truck and the stuff clings tenaciously. It has not washed off at all.

So, I do it myself...and use Fluid Film simply because it's cheaper for DIY. Not as good as a quality job from a professional with a lift, but definitely better than our regional Krown business.


Was that an Ohio shop?
 
For guys in Ontario, check out your local TSC Store for Rust Cure. It is thicker and holds up much better than Krown. I got their cans on sale for $5 each.
They also have a DIY kit with a gun and they often go on sale too.

They do make a good product. I've used their aerosol before on the Snow Blower and various other areas. It's good stuff and it's clear.

Has anyone here been to the Krown of South Central PA?


This is the first time I've heard that. That place is only an hour and a half from my house. I might have to be the guinea pig on that one; this is the first time I've had to drive my GTI through winter muck and I'm not happy about it...

It's not about manufacturing costs, it's about people buying the product and I have a feeling very few people DIY rustproofing. TSC is a tractor supply store geared towards farmers, they are more likely to rustproof their farm equipment themselves, but it is still a small market.

But then, Krown will want between $120 and $150 from you depending on the size of the vehicle and depending on the shop, may not even do that great of a job. That $65 jug is more than enough to do one vehicle and from my experience, I used the most product during the first application, subsequent ones used much less.


But, If you want an even cheaper rustproofing oil, check out Monarch Oil in Kitchener. I paid about $20 +tax for a 4L jug of their stuff. From talking to them, they make it by themselves and sell it to local farmers, heavy equipment operators and plow truck owners, that is why it's so cheap.
It's good for undercarriage, but too thick for doors, trunk etc. So I used Rust Cure in cans to treat those areas.

You could always use warmed Petroleum Jelly. It will go on well warmed to a liquid (Just sit a jar in hot water) and then spray it using a spray bottle. There is a guy on the web that is doing that and it seems to work and seems to last the year.

It's not clinginess but creeping ability that is important IMO. I don't care about how sticky it is, I want it to creep into every pinch weld. If you're from Toronto I'm sure you've seen many cars that are oil sprayed more often than they are washed. If you can see it creeping onto visible exterior surfaces imagine how it permeates locations where it is directly applied.

Krown is legit. $150 a year is peanuts when it pretty much eliminates sheet metal corrosion in the rust belt.

Wait till spring, wash the salt off chassis real good. Let it dry for 2 days and drive it out to Krown.
Clean and dry is the best prep for the rust inhibitor.

That's all I use and have been since the 1980's. The 1986 Caravan I've posted pictures of here before went to the scrap yard 22 winters later with 460,000km on it and 0 rust thanks to Krown.

In my above reply to George I didn't realize I already steered him towards Monarch Oil, my bad.

In regards to the creeping ability, it creeps just fine.

Here is a pic of the rear fender of my Mazda 3 after I sprayed it with Monarch Oil rustproffing. This was several years ago, so I don't remember if I took the pic few day or a week after treatment. But the point is that it creeps just fine and stays put in high wash areas. Krown is legit, but it washes off relatively easy.

I own a 2003 Dodge Ram 1500 Long Box PU bought new. To date there is Absolutely ZERO rust corrosion on any of the sheet metal. I thank it to the $79.00 X 2 5 gallon pails of rust proofing oil I bought years ago a my local Napa. I admit Crown is a good product but cheaper rust proofing products work too! The money I saved over the years buys LOTS OF PEANUTS!
 
If you guys are drilling holes and spraying body cavities I would love to see a thread on it. If you can actually do a pro style job for cheap that is awesome!

I was always turned off the cost of the undercoating gun, and the general grossness of the process. There was also a recent thread where the poster was concerned about inhaling a lungful of Fluid Film while undercoating their car!

South Main Auto does all this.

+1

Why are those guns so expensive? Even at Harbor Freight
 
Tried out the aerosol cans. Comes out clear. Spray from 6 inches away and the aerosol disperses nicely leaving a controllable strip of coverage that doesn't run. Get too close and it makes a dripping mess. Doesn't smell strong but If you get it on a cat, it smells like fish burning. So far so good.

When you DIY no drilling is required as there are plenty of access holes and factory plugs that can be utilized. Places like Krown drill for their own convenience to speed up the process.

As far as cost of the undercoating gun, you mentioned that dropping $150 annually is peanuts to keep the car rust free. Well, you can get some very nice undercoating guns for about $200. Basic ones, with no wands run from about $30 and ones with a wand or two, about $70 or so. Not sure what type of guns you're looking at, but even at $200 the return on them is very quick, especially if you have more than one vehicle to treat.

I spray the aluminized parts of my exhaust on my vehicles from the after the cat back and then wipe off the excess and run the vehicle. When I'm under there in the winter changing the oil the exhaust retains a greasy looking exterior black haze and IMO extends the life of the exhaust parts.
