When buying a new car, is it good to have the car sprayed with rust proof?

Question

Okays, I am going to buy a new car, and I was just wondering if it was good to purchase the rust proof spray package. This package is where they spray the outside and bottom of your car to protect it from rusting. I live in Minnesota, so is this really worth purchasing for 700 dollars?

I guess my real question is, does it really work?

Answer 1

I always purchase the rust proof package it extends the life of the body.

Answer 2

For $700.00 the answer is a definitive, NO.......

You can buy the undercoating and do it yourself for $30.00 or less.
The car probably comes with a 100,000 mile rust through protection.

The concept is good but the $700.00 price tag isn't..

Answer 3

Yes, in my opinion Z-Bart is the best. In your locale, it is definitely a necessity.
