rust proofing...
When I bought my cobalt last summer I got the option from my dealership to have the car rust proofed. They claimed that it is permanent and that I will never have to rust proof again. In the past, I used to have my car rust proofed every year by a company called Krown.www.krown.com They would spray oil under the car as well as drill holes in the doors and pump them full of oil.
My question is, should I still go ahead and get this done, or is the one that the dealership did good enough for the life of the car?

Actually this is a common practice in Ontario too, around the great lakes. I would say no, dont do it. Just keep your car clean. We do SGI safety inspections here and when we see those cars, I cringe. Everything is covered in oil, dirt, leaves, bugs and whatever else can stick to that ****. However, there is no rust lol.
They just coat everything in oil Tyler.

i do that at the dealer i work at, undercoat too, i think it works, the reason the dealer is so high in cost is you are also getting a 10/100000 mile rust through warranty (well, atleast for chrysler thats why) i did it to my truck and ill let you know how it holds up in WI

Even here in Ohio there used to be lots of rustproofing places but they are pretty much all gone now.
They would usually use a hot mixture of thin tar and oil and drill holes all over the place to spray the stuff in. Ironically, drilling those holes gives rust a better place to start.
Lots of people don't think that extra undercoating is necessary anymore. On the Cobalt, the only body panel that is not double-sided galvanized is the roof. Also, the designers work hard to eliminate places where water/mud/salt can collect and cause rust. That's why most new cars now have good rust-through warranties.
I drove my Cobalt through 2 winters and did nothing but get an underbody spray at the car wash every couple of weeks or so and it looked almost like new underneath when I sold it.

My old Beretta was supposedly double galvanized too. It's almost 20 years old, and has no true rust... only paint corrosion! We can only hope the Cobalts hold up the same way....

If you plan to keep the car forever it might be worth it. When you go to sell the car you might be able to get more $$$ if you can prove you got the undercoating.
Isn't the rust warranty 6 years?
Personally, I worry more about the body behind the wheels, where rocks and salt can chip the paint.

I guess in the end it doesn't hurt to have it done, even if you had it done the intial time you bought it at the dealership. I just don't like the fact that they drill holes in your car. But then again, I had it done every year in my last car and it went 9 years with-out rust.
Up here in Toronto Canada we get hit really bad every winter with snow, and the roads are just covered with salt. So in that sense I guess it works.

there are better alternatives to oil spray. there is a product called counter act. what it does is creates a charge through the entire can and prevents it from rusting. it has 2 little pads you put at oposite corners of the car and it wires to the battery, or you can plug it into the wall if the car is in storage. it draws very little power and has an auto shut of if the battery gets to low for the car to start. and for those sceptical, a friend of mine has a 67 mustang project car. the car was acid dipped and after a week in bare metal the car was getting lots of surface rust. installed this and scotch brited the pannels, not a spot of rust since, and its been 2 years.
