RustProofing

[Peter912]

Did you feel the need to have your car rustproofed or are new cars treated against rusting in the factory better nowadays than they were in the past ?
One doesn't see as many rusty cars on the road as there were years ago .

Couldn't risk it because of the salt in the winter and all the water humdity, I got the 10 year paint protection / rust proofing from the dealership but I missed the first yearly checkup so the warrenty is void, I then went ahead with the Counteract rust proofing device, we'll see with the years if that works or if it's a scam.

How long do you plan to keep your car?

Chances are if it does begin to rust it'll be pretty far down the line. There aren't too many instances of major rust here on EXD.

I wouldn't get the rustproofing.

Here in Montreal, they use more salt like there's no tomorrow. On Sunday morning we got ~2 cm of snow and all the major roads were already salted down by 9:30 in the morning. I washed the car on Saturday and it was salty gray by last night. My wife loves the Elantra so we plan to keep it a while, so we're rustproofing just in case, cuz it's so friggin salty.
The dealer wanted to sell some weird tar coat or whatever and it was pretty expensive, but I opted for Krown yearly treatment instead. Since we started new, as long as we do it each year, replacement of in-to-out rusted panels are guaranteed forever, essentially. Plus if you're in an accident and get any body panel repaired/replaced, they'll respray that for free.
That's just me... if we lived out west where they don't use salt, we wouldn't rustproof.

I apologize, I have nothing to contribute to how to rustproof..

more a question about how to repair rust, if any of you know. I have three rusting spots on my 2000.. two of them are on the little metal strips that seperate the back windows from the little triangular back window, and the third spot is on a tiny dent on the trim underneath the driver's side door. The latter is a rust spot maybe 3/4 of an inch long, 1/4 of an inch wide. The two on the window strips are pretty much the entire strip. I'm not sure if I have to worry about those because it's an isolated spot, but the one under the door I worry about.

What would be a wise way to go about fixing these spots before they worsen?

[mtlelantra]

Sand off the rust completely, then spray the clean, bare metal with zinc galvanizing spray. Then refinish with paint/clearcoat.

[Meganap]

Thank you for the advice - I'll head to Autozone and look at some of their stuff.

My only other question is about a possible rust spot starting - I recently had my window regulator and motor replaced on the rear left window, and to do this we had to tear off the inner door lining completely. We sealed it back up best we could, but it was a pretty shoddy job. We've had a ton of rain and ice since then, and I know for a fact that tons of water has gotten down in that door, because the window seal on the outside has always been sort of wonky, and now that the liner is mostly gone.. will my door start rusting from the inside out? :/

[mtlelantra]

There are drain holes at the bottom of the doors. Just make sure they aren't clogged. You could always spray some Rustcheck lube or some other sort of water-displacing spray through the drain holes to force out water from the seam along the bottom of the door.

[Meganap]

Cool, thank you.

Just another perspective, I got the rustproofing and found that my car is noticeably quieter than an Elantra that I got as a loaner car that didn't have the rustproofing.

[bdiggy]

I say it's all a money scam. Salt or not, today's car's have so much freakin' plastic it's near impossible to rust like an old car would. That, and a few coats of quality wax in the warmer months will keep it safe through the winter.

[04 elantra cvvt]

That, and the newer cars are sealed a lot better. They didn't spend nearly as much time on the older cars making sure that every square inch of the car had paint on it.

**** that, I have rustproofed every car ive owned every year before winter

its the UNDERBODY that rusts.... give me a car that has a plastic frame hahaa thats what i thought.

lol, i agree with felix, canada does have harsh winters and can really *uck a car up any car, the only car i can see withstanding the canadian salt and crap, is a volvo, with the quality of their paint no one can touch them because they are made for scandinavian winters and those are even worse than here in canada. but rustproofing DOES hellp at least my family saw it, on my brother's old 03 accent.

Chiming in a bit late but I recently bought a 2002 GT and just had it rust protected at Krown-Rustproofing.

I'm in the Montreal & Ottawa areas of Canada. Drive a freshly washed car for an hour in January and you can wipe your French-fries on the body panels to add taste... it's that bad up here for salt.

I've seen an unprotected car rust out in five years (perforations) and a protected one last ten years with little or no signs of rust.

We'll see in another five or ten how my 2002 Elantra does but I'm putting money on Krown doing what it should. It's cheap insurance.

I think the Crown spray is a little too environmentally friendly. Two months after spraying I couldn't find get any sign of it when feeling up inside the fenders. I now use a local body shop who's oil spray seems to last much longer. Both my Hyundai's also have a "Counter Act" electronic rust inhibitor module. It only draws the same power as a digital clock, around 55 milli amps. These units were $600 + a few years ago, but the patent is off now. The local Hyundai dealer now sells them with their new cars as an option. Salt and Canadian winters kill cars fast.

I visited a Hyundai dealer last weekend and noticed at least one of their cars had an electronic rust inhibitor installed right from the showroom floor. Seems like a great idea. Similar concepts have been proven in marine and civil engineering applications for years. (sacrificial anodes for underground pipes, for example)

FWIW, it's been a few weeks since I had Krown done. It's still stuck to the underside of the car and seems to have congealed a bit but who knows if it'll last. I'm concerned taking it through a car wash with an underside spray will blast it all off. We'll see.
