well... the color of poo and plasti-dip is just a tad different, but plasti-dip would look more in place than the grey tail lamp bezels...
From a distance plasti-dip looks ok but up close it looks textured and cheap.
I'd rather keep them as is, paint them, or buy the OEM parts.
I'll probably just end up leaving them until I can find a good deal on the OEM parts. The grey matches the silver just fine until then.
