I live in the cold in Ontario Canada. I think BMW gurantees no rust for certain amount of yrs. Since mine is bout 4 yrs old, I was wondering if I should rust proof it? Please let me know your opinions and experiences, thanks.

Me too. I'm thinking about doing the same thing.

Would you use Rust-check? I've used them in the past and have been happy. But in this case I think I would insist that they don't drill any holes. I'm sure BMW would go nuts at me if they did. Thoughts??

Thanks

yea, definitely dont want them drilling holes. And dont know which company to use?? I also didnt want the bottom of the car to be oily and be a big mess when working on it...........

I wouldn't do it , it just adds a bunch of weight and these cars rarely rust..........the rust warranty is 10 years I believe ...............better idea , move to Vancouver

My vote for aftermarket applied rust proofing = :thumbsdown:

BMWs are produced for climates and driving conditions that are harsher than what you'll probably experience. Keep your car clean and wash corrosive salts and road treatments off with clean water when practical or use a commercial car wash from time to time as long as they use well-filtered water - so you don't bathe your car in a salty brine.

I'm also in the GTA and just bought an 05. I was thinking the same thing but after some thought I will pass on the oil spray. I'm storing my car this winter but may drive it next winter. I have a big problem with holes being drilled as well. I'll just trust the BMW rust warranty.

All good advice. No business for Rustcheck.

For what it's worth, the TR7 (see below) was dunked in rust proof a number of years ago and is still rust free at 29 years old. But that's entirely different engineering.

Thanks a bunch.

Lots of great advices! I think I will deal without it this winter and hopefully I can just park it next winter. Thanks again for the all great info.

rustproofing is a scam, but if you must do what we did in the good ole days in Vermont: spray the underside with used motor oil.

+1 I dont know about canada but in us they have rust warranty ...

also it doesnt rust that much since we have some undercarriage covers...

just wash cars whenever snows or go over salt...

no need to spend money on that rust thing...

just go make it go faster!!!
