My old bumpers, rockers and my spoiler are just getting total chip city. They put so much sand on the roads during the winter, that it's like driving through a sandblasting factory. I will have to repaint all the black parts this next winter.

So has anyone tried the Hardnose paint? Is it to glossy? It's $45 a Quart.

I've not had any experience with the hardnose paint.

But the standard Por-15 as well as the Wurth product will oxidize within a few months.

I personally would consider powder coating it.

Powder coating is good for the bumpers BUT I don't think you can powder coat a fiberglass spoiler.
