I would appreciate any insight that anyone may have on rustproofing. I’m the second owner of a '97 240sx SE, near showroom perfect, and have owned it since 2000.
The car was originally sold in Florida, and spent most of its years there. One year ago, I moved to Toronto (ugh!) The car was driven on a few dry days during the winter. I pressure-washed the undercarriage within days of it being driven each time during the winter, to keep the nasty salt off.
It will never be driven in the winter again, but I’m concerned about the chance of it rusting underneath. Here are some questions:
Was rustproofing applied at the factory for this make/model?
What are the pros/cons of having an 8 year old car rustproofed (aside from it not rusting - LOL) Am I wasting my money at this point?
Is rustproofing even necessary, since I won’t be driving it this winter?
Is rustproofing and undercoating the same thing?
Aside from price, what’s the difference between the small shops that charge under $100, and the stealership which charges over $600?
1.) -?
2.) Peace of mind?
3.) Yes, moisture/humidity changes exist everywhere
4.) no, Krown rustproofing would be the best, most use oil spray stinky/dirty
5.)Krown is the best, price unknown. I believe dealerships send them out and charge on top of 3rd party services
Krown costs around $120 per application.
Too late for your car, but if you start Krown when the car is new and continue the service, they give you a rust protection warranty…
I prefer the Krown too, it’s good stuff!
Although, for them to properly apply it inside the door sills etc etc they will drill some holes, spray inside the holes, then put some factory looking plugs in the holes.
This bothered me at first, until they did it and once I saw it I didn’t care.
Not true. Krown or any other lubricant will inhibit/slow down rust from forming or spreading. It’s never too late to underspray your car. If you dont want to drill holes…which you may not since I doubt there’s major corrosion happening and you won’t be winter driving have Krown do the underspray only. That’s 50 bucks last I checked and only needs to be done yearly at most.
I doub’t you have anything to worry about but a little prevention goes a long way. I spray mine yearly even though I store the car for winter.
ps. theres a Krown on Parliment Street just off Lakeshore. I pay cash there and the guys don’t charge me tax.

I think he meant its too late for the warranty since its not a brand new car.[/quote]
Correct, I meant too late about the warranty, sorry for not being clearer!
Rust proofing anything is always a good idea![/quote]
Gotcha, my bad. Even still they do offer a used car warranty for cars up to 3 yrs old for up to 60 months…still not enough for your '97 but cool nonetheless.
Krown is supposed to be “dripless” in that the oil penetrates the metal…but I’ve yet to see any kind of truly dripless oil product. There’s other ways to go such as tar based products but if you have rust already forming then this is not for you. It’s great for new cars and wheel wells though!
