Is Krown Rust protection a good or bad thing for an M35x in Toronto area?

[fooitm35x]

I think to get rust protection from Krown, is it a good thing to do or I shouldn't bother?

The only body panel that can rust is the roof. Everything else is aluminum. I think a good paint sealant / protectant and waxing is more important.

I believe the hood is the only aluminum part. All aluminum is a nice thought though...

all newer cars use zinc coated steel when aluminum is not used. Rustproofing is a nice way to make your dealer richer. My understanding is that the rutproofing actually clogs up the drail holes strategically located and manufactured into your doors, hood, trunk, rails etc. and TRAPS moisture, thus enhancing the creation of rust. I believe all manufacturers now offer 10 years/unlimited mileage rust warranties. Here in Arizona, I bet we never have had a claim!

save your money or spend it on paint detailing and good wax. And a vacation here to golf. And meet Ken in AZ.

In Toronto they only use salt , But if you past 400 and HWY 7 North they use a salt and brine mixture ..eats metal like krazy ..krown is worth every penny > here is a picture of my 12 year only 4 runner with 400 K ..done every year at krown ..i got my money's worth

So is it true rust proofing -- or just an undercoating on the undercarriage? There is a BIG difference. Rust Proofing entails drilling holes in all the panels and spraying crap inside (which then clogs the factory drain holes), and also includes spraying the underside. Based on the single pic of your 4 runner, it would appear that Krown is just an undercarriage coating?

I used Krown rust protection once on a previous vehicle and I live in the GTA. I am a supporter of the product, however, the main store up in concord f'ed up my paint because they applied it liberally and didn't wipe it down properly. This was a brand new car. I noticed that shortly after when attempting to wax the car around several areas of the hood there was a while milky haze embedded in the clearcoat. I could not get rid of it at all.

If you get it done just make sure it's cleaned up right away.

With my M I haven't taken it in yet but will and will get it done at RustCheck facility. I know the product is more runny but it has the same chemicals to slow the progression of rust and it's easier to cleanup in the spring compared to rust check.

I also have the electronic module as a secondary piece of mind.

Yep. Krown drills the holes and sprays everywhere. I mean EVERYWHERE there is a cavity in the body panels! As I said in my previous post I will never use them again for two reasons. 1. They ruined my other brand new cars paint clearcoat, which by the way I did call them, email them and go no response. and 2. The chemical they use is too tacky.

I prefer Rust Check's runny substance more because it's easier to clean up in the spring/summer.

CHEERS!

I don't know how familiar you are with the GTA. It's a shop between Bayview and Leslie on Finch Ave. Beck Automotive 630 Finch Ave East. That shop's CAA approved too. http://www.beckautomotiveltd.a...=home

You are correct and my 2008 M sales brochure confirms that the car has "aluminum doors, hood and trunk". However this does not mean that only the roof is steel. The front fenders and rear quarter panels are probably also steel, since they are not mentioned. Rustproofing might be of some benefit in those areas.

Having said that, I have not used after-market rustproofing for at least fifteen years. I drive daily in the Toronto area with all its winter salt. I tend to keep my cars for five or six years, but sometimes as long as 10 years; and have had no body rust problems. Many people swear by Krown or RustCheck. In my experience, manufacturers have significantly improved their techniques to prevent (or at least slow down) rusting in the last decade. I really hesitate to fool around or compromise with the original design, especially when it involves drilling holes in body panels. Unless you are keeping your car for more than 10 years, I question the need.
