I maybe wrong but older Mazda tend to rust very badly inside out. I bought my new Mazda but did not get the added Rust Proofing for it. Not sure if I should get it sprayed with oil from a local shop. Any recommendation or good place to go to? I'm located in Markham Ontario Canada.
Cheers!
Hey Andre,
I'm in Ontario, too, and have thought about this...I suggest you poke your head under your CX-9 and take a look at how accessible the undercarriage is for spraying a Krown coat (or similar). There are a series of panels and covers, made up of a sound deadening material...probably also helps with aerodynamics. Unless your installer (or you) are willing to carefully disassemble these covers, I'd guess you will not be getting a proper treatment.
I did vehicle spraying as a side job in college, and it's about turning the cars quickly. Taking the time to remove panels is not what they want. I'd guess the installers would get their skinny wand, jam it strategically under panels and give a squirt...knowing you will not disassemble things to inspect the job.
As for the doors and rockers...It's a toss up: The protectant can help in these areas, but they usually need to drill holes in your shiny new truck.
Look into a product made by AMMO. You can coat the car yourself with just a microfiber towel these days.
For what it's worth I believe that modern cars are properly treated at the factory via the 'dip' they get in the manufacturing process. Additional materials sprayed by most of the aftermarket shops just serve to trap moisture and ensure that you'll get rust in odd places eventually. A very complete wash and a good rinse of the undercarriage on a regular schedule would serve you better I'd say. Of course, take care of chips and nicks in the surfact paint to prevent rust from the outside in.
The usual rust trouble areas from the past are totally covered with plastic body molding front to back on the CX-9. And much of the bottom of the car is covered in plastic panels. I wouldn't worry about rust.
