Has anyone painted their engine covers? I figured it would be easier and less likely to fail than painting the valve cover. I wanted to add a personal touch without going too ricer so I stuck to a nice aluminum finish on the centerpiece and left the left and right sides original plastic and also left the emblem original chrome. I also hand-painted the SKYACTIV since it would be a real pain to spray paint. If anyone has done this yet on their Mazda I'm really curious to see what you did as far as color scheme. Thanks!
