I do Powder Coating on the side. I can do it cheaper and faster than the big boys. Below is a link to some samples of my work.
A one standard color valve cover (SOHC) will run you 50 bucks. That includes stripping, prep, powder, and shipping back to you. The translucent/ candy colors are a two coat process and will run you 60 bucks for the same service just with the two coats (reflective base -color top coat). I can do anything metal that will fit in my oven and that is worth shipping. Just pm me for more info.
