Since you live in Canada,I think you should get rustproofing.I got my rustproofing because I have to park my car outside and I drive it a lot plus it gives me peace of mind about rust coming on to my car.The only downside is that the rustproofing doesn't dry immediately so it can drip and when you open the doors,trunk,etc,you can get rustproof on your hands like how I did....Like a typical Canadian,I got my rustproofing down at Canadian Tire.

 

i did it.
the shop recommended that it be done once a year, but i think once every two years is good enough.

and SupremeCorolla is right, it wont dry right away. I got mine done in July, and it finally just stopped dripping.

I got mine done by Krown

 

without a doubt it is the best 129 bucks youll spend...and like mike above, i exclusively use Krown.

I had a 1996 Ram that had rust under the driver door when i bought it used in 2002. i had it krown'd every year (even though they say ever 2 is fine), and it stopped the rust dead in its tracks. it never got any worse, never spread, and no other rust ever showed up on teh truck. the tranny died and i ultimately sold it to my mechanic friend and we rebuilt the tranny. the thing is still going strong with the new tranny and the body is in amazing shape.

anyone that kows the dodge's of the 80-90's know that sheet metal was not their strong suit.

Krown works. trust me. Do it.

 

Depends how long you plan on keeping your car.

 

Up there you can get "Krowned"! Its the way to go. Too bad we don't have that down here.

On used cars that may be showing some rust I use fluid film shot from a pressure sprayer every fall/every other year.

If there is no rust on the car, why bother getting it rust proofed?

 

Did you really ask that? :facepalm: How about to prevent rust from forming in the first place.

I spray the underside of mine myself every couple of years.

 

Get it done once every 2 years but wash you car every now and then especially immediately after Winter.

 

For most cars, it is a waste of time anymore. My RAV is a 2005 with 150k. If it even looks like it might snow, they are dumping truckloads of salt on the street. Now they are dumping brine, which is calcium chloride. Nasty stuff.

The body looks great. No rust and it has never been in the garage. What really takes a beating is the suspension parts and some of the engine parts. They look nasty and are caked with rust, but rustproofing won't stop this.

Honestly, your best defense is to wash the car a lot in a drive through car wash that uses clean water. Many use recycled water which just takes the salt water from the previous 10 cars and washes your car with it.

Also, I would not rustproof it if it has been driven for a few years in salt. It just seals the salt into the corners and will probably rust out faster. You need to do it when the car is first purchased.

 

It's one of those things I would consider doing on a high end or rare car that had to be driven in the winter, or if you're set on keeping your car for 15+ years... I'm in NE Ohio and they salt/calcium constantly. My truck is 10 years old and has 110k miles, and is driven in the winter more than any other time (also sits outside) no ounce of rust anywhere on the body (but of course there is in the undercarriage which is totally normal). Same story with my old jeep I got rid of 2 years ago. Both vehicles I washed maybe once or twice a year Basically what I'm pointing out is both were exposed to the worst conditions for salt/rust and still never developed rust on the body. I think in many instances the rust proofing is very much a placebo effect. I'm not doubting that it works if your religious about it and get it done every year, I'm more so just doubting the value and point if you only plan on keeping a car for so many years.
