+1 on the grey.
Btw, I'm going to do the very same job on my windshield this winter, and I'm tempted by anodizing, instead of powder coating.
To my knowledge, painted aluminum on boats is never going to last, no matter how well the paint/coating job is done.
Ideally, alu lasts forever when left natural, but the second best is often considered the anodization.
Any views on that?

my advise... get a spare and do it... you may not like it for everyday driving... at least that way you can go back...

shows everything, dirt, scratches, looks great when new though!!!

I like annodizing as well, but it fades in the sun.

gray would not be as hot as black......my .02 cents

You are probably right. I don't like the gray enough to go through the hassle and the black will probably leave 2nd degree burns in the Texas heat. Sounds like I am passing on this project. Thanks for the feedback.

I always have been a fan of the white. May sound boring but I think it just flows better when it matches the majority of the above the rub-rail color? But my second favorite would be the gray for sure!!
