Father Krowned a Buick lesabre for about 7 years and the brake lines rusted out so we go with whatever is the cheapest option, around $50.

Spring is still too early for rust protection. Plan for a DIY project with a compressor, a blow gun and a jug of Corrosion Free in Fall.

Sorry ... This can be debated....

Krown mentions that best time to do rust proofing application is spring.
It is the time when temperature rises and rusting process accelerates. If at this time, the car is washed and sprayed, the rust prevention is at its best. When you spray in fall, the spray gets washed away in winter months ( And at winter months in sub zero temp , there is not much rust development) ...

There should not be no salt left over past winter. I like to clean up the salt deposits in early spring, when it is warm enough for the pressure washer to work.

I wish I could do this even during winter after the snow fall, but there is no coin op car wash around that allows for a quick connect attachment. I don't have enough space in my garage.

"Corrosion free" was tested by the Canadian Military with good results, but I can't find the link.

All the local Vancouver area cars seem to be fairly rust free. Most of the rusty ones came here from the eastern provinces. Noticed the location from the car lot stickers on the trunk.

The only rust I really see is on pick-up trucks, when they are using the boat ramps.

It was DRDC (Defence Research and Development Canada) that did the study. Here's a link: https://shufti.files.wordpress.com/2010/05/p526285.pdf

I use Corrosion Free Formula 3000 to "touch up" my car from time to time - spraying in the holes at the bottom of doors, in door sills, and opening frame plugs up to coat the inside. My mechanic uses a similar product (sticky, oily) to for undercoating. He indicates that he doesn't use "rubber" type undercoatings as he's seen them trap water next to the frame and cause hidden rust damage. Thus, he uses an oily product that displaces water.
Yes, the rubberized stuff will indeed trap water and the car will actually rust more.
Lots of people empty out couple of cans of the rubberized stuff before they sell their car...it does great job at hiding rust, but those who know better will walk away from those quick cover up jobs..
