Corrosion Free , which package?
I know Mazda 3 rust quite easily but I got a 2010 Model made in Japan and red the issue has been corrected from that year.
For precaution, I was wondering which Corrosion Free package should I get? I'm able to do the doors with a Rust Cure Formula 3000 can from Canadian Tire but can't do the undercarriage. They have 3 plans where I'm going : 70$, 100$ and 140$ (Link to details pic). The middle package is a waste of money, they apply a layer at the bottom of the door (not inside) and under the hood. I can do myself easily with a can with in 5 minutes. I can do many of the top package but fender braces and rocker panels might be hard to reach with a can.
I'm a bit late this year but I just bought that car. There is a electronic rust protector installed on it but as far as I know, It is proven to be mostly a gadget.
Which package would you go for?
