Ive never painted them myself but many members on here have painted them. You can do it yourself, you should be able to find the right paint at any automotive store.
Ex. Discount Auto Parts, Pep Boys...etc.
Truplatano i should be finishing mine in a week. I got some pic already give me a week. I'm done with the rear. Just got to do the front. But for quick notes. I sanded my down cleaned them of coarse after sanding. I shot them with high temp primer and then shot them with high temp paint. Then clear coat them . I used my dremel to sand down the calpiers. I'll get some pic up maybe today. Hope this help
i use duplicolor I'll try to get pic up for u today. It will just be the rear calpiers for now though. The weather here was to crapy for me to do the front ones. All the front ones have is primier for now
