Yep, Bug boxes are acording to the book painted same as the engine. My orginial bug was painted as well and I know it was never out of the car till I did it. Anyway alum will corode, white powder stuff if not protected in some way or cleaned and washed from time to time. No way to do that in the tunnel of course. The alum. diff, is also painted, black. Other engine alum stuff is unpainted.
