All I can say is, welcome to the Mazda Rubbish Paint Club. I bought 2014 Mazda 6 Sport Nav in dark blue. What a mistake...
I have had very many cars over the last four decades, and have NEVER had a car with such poor paint. The colour coat is about as thick as a cigarette paper - probably not even that - and of course, the primer underneath (why is it always white?) shows with every tiny nick. The front end has literally dozens at 18 months and 18,000 miles, some of which show signs of rust. So the weekly routine is hand-wash with a soft fleece, minutely inspect for new chips, and touch them in. Worse, I have four tiny chips on the roof, two which now have rust tracking under the paint, the other two are beginning to rust. How does a flat, horizontal panel get stone chips, for goodness sake?
I'm convinced that if a butterfly walked across the paint it would leave footprints. I would never dare use an auto car wash!
Mazda don't want to know, other than the dealer selling me a paint touch-in kit. So much for paint warranties!
It's a very great shame, the car is well equipped, comfortable, quiet, and excellent to drive, but BADLY, no, make that VERY BADLY let down by the paint finish. Not good - it's not a cheap car.
And it's not just me, a friend has similar problems with an MX-5. Contrast this with my hack, a Golf which at eleven years and 160,000 miles has six stone chips - I just counted - and no rust.
Mazda? Never again.
