Small rust is forming on my factory side shirt, where the bottom part of my door covers it (front and back). I have seen many older Mazda 3's have rust lines coming from these areas below the doors which concerns me.
I have a 2012 Mazda 3 and I would like to nip this in the butt before it gets worse. However, I do not have much experience with body work and am looking for any suggestions or opinions on the topic.
So if anyone has an older model Mazda 3 who has addressed this problem I would greatly appreciate your input, thanks
