Rust Proofing

[2008MDex]

A while back I posted a question about whether I should bother getting my 2008 MDX rust proofed? I bought this thing used last year. Figuring I will keep it for 5-6 years...rusting proofing is $100...why the hell wouldn't I right? Any specific reasons why I shouldn't. I guess the other question is have any of you never rust proofed your MDXes and after 5-6 years still just fine. Note: I live in Toronto, Ontario.

Most cars today are well protected. While it is probably a waste of money as far as the vehicle is concerned, some people feel better when they spend money on their cars. If it will make you sleep better go for it. Your car will sleep well with or without it.

Did u rust proof your last vehicle?
I think prevention is best. wash undercarriage as often as time permits. road salt+over time=rust.

Well I'm a VW guy. Had two back to back 300,000Km TDI Jettas. Still running the 2nd one and they really don't rust until WELL into year 13. MDX costs about 3 times as much so yeah spending $100 on RPing would make me sleep better actually. I spend that much on coffee.

The metallurgy and coatings used during production have come a long way in the past 10-20 years, so they now provide better protection when it leaves the factory than anything you can do to it afterwards. Your car doesn't need rustproofing. Don't waste your money.

Consumer Reports a few years ago showed that rust proofing actually caused more trouble than good. It can trap water in new places according to them. And as others have said, cars are much more resilient to rust. I'll send another post, spend the money on good car washes. Even in salty MN I rarely see rusted out cars.

There you go. If you keep the X for 5 years that will be only $20/yr. Happy Zzzzzzzzz.

I have been using Fluid Film for years on the under of my car..I have an 1988 volvo 240 also, with 445,000 on it, and there is no rust whatsoever on the bottom of it. Around here its, about 10.00 a bottle or so. Fluid Film® | Corrosion Preventative, Lubricant and Rust Inhibitor Well worth it. Spray it once a year or so and your all set!

As several members have stated that modern car really don't need rust proofing. That being said, it is very important to give the car a thorough wash after each heavy snow. You want to wash away the salt underneath which may attack brake components, wheels and other exposed parts.

I've heard frequently that rustproofing can block various drain holes that are supposed to be open, actually causing rust.

Even a small amount of snow may prompt the municipalities to give the roads a good dose of salt.

Until a heavy rain washes the roads down you will be picking up salt. In the spring I drive through some deep puddles with enough speed to clean off the salt.

Years ago, when cars commonly rusted, beach dwellers would put a lawn sprinkler under the car when they got home.

I am in Toronto and have my cars rust proofed by Krown every year. I would recommend it. My friends don't do it and their cars start rusting after 5-6 years. It is a good investment if you plan to keep your X past 6 years

My 2004 MDX has never been rustproofed. It spent its life in Grand Rapids, Michigan before I bought it and moved it to Chicago. It now has over 135K miles on it. And not a speck of rust.

I've lived in Kalamazoo (MI) , Chicago and finally in Ottawa (Canada)...Canadians use a lot of salt which accelerates the corrosion. I believe in Kalamazoo, sand was used which created more of a mess but did not corrode metal.

Ever since I got back to Canada, I've been using Krown and my 12 year old civic had little bit of rust (size of a dime) which started after my front windshield replacement.

So to answer OP, get it done. I use Krown which comes highly recommended. BUT ask them to apply silicon to the door seals as repeated application can cause them to sag over time.

Grand Rapids uses salt.

You don't need rustproofing on an MDX. Save your money!
