This DOES NOT look like stainless steel.

It's zinc alloy.

Edit: BTW I have a black evic which did the same as yours but took a year to do so.

I also have the Pearl white and the paint on that one has held up much better.

If you decide to repaint the mod it will be difficult as zinc does not like many acrylic paints,will never dry hard.

Need a zinc based primer and or paint, epoxy paints should also work.
