I have chrome wheels and i work offshore and park very close to the Gulf of Mexico and the chrome wheels i have now are already pitting after 1 year so i and looking into maybe a machined and black rim but need to know before i spend that much money that they are durable and can handle this kind of beating or is it the same and will pitt under the paint, and are they painted or powder coated i can not find any info on if its paint or not only a couple say if they are painted.
