Rust-Proofing - Globe and Mail Article

Check out the above article in the globe and mail today.  Oil spraying is another term for Rust Checking or Krown Rustproofing but I'm not sure where the author of this article researched for this???  As far as I know Rust Checking or Krown involves more than spraying used oil on the underside of your vehicle.  They drill little holes and spray the stuff all over the place, most older cars you see around with the rust proofing stickers on them look great.  The cars are probably worth less than the rust proofing that has been applied over the years but they look good regardless.

Personally I am not a big fan of rust proofing, it is fairly expensive, messy and is more useful for people who want to keep their cars for 10 years or more.  Most new cars these days are built to resist the formation of rust unless you get chipping from rocks or other debris which rust proofing will not protect you from.  The biggest rust proof scam going is the dealer applied undercoating..... it's a total money grab for the dealership, don't take my word for it research it for yourself.  If you want to rust proof, the annual Krown treatment would be recommended by most.  I wouldn't go with Joe Bob's Oil Spray or whatever the heck the author is referring to in the article!
