And the rust begins...

[pingwin77]

I just noticed that I am starting to get some rust in the corners of the wheel wells where the plastic bumper meets the metal. There is a little bit of paint bubbling but not a ton. What is the best way to take car of this so it doesn't go any further?

Pull the bumper, grind off the rust, clean it real good, and hit it with some sealing primer, before it gets repainted.

Don't these cars have a 10 year warranty against rust? I'm pretty sure mine does.

Edit: Looks like only 5, that sucks: http://www.edmunds.com/used/2004/mazda/mazda3/100364240/standardwarranties.html

Mazda also says it's only against rust that causes holes in the panels, not just surface rust.

Your car is a 2004, isn't it Mike? Consider yourself lucky that you've only gotten what rust you have, these poor Canadian bastards have it way worse:

I'll be pulling of my front bumper this year to do similar rust repair. I did some last year, but I guess I did not do it will enough. Time for round two!
