Instead of painting or plating, you could always google "vinyl decals" or "vinyl adhesive sheets" and wrap your pv. I did some of my other pv's in a blue and black carbon fiber scheme. They look nice and when the wrap starts to wear out, just peel it off and re-wrap it. It's a decent non-permanent method. Vinyl can be had in any color or pattern you want without risking damage to your precision pv.
