Alright, I have some serious powder-coating connectionz (girlfriend's dad!
) Anywho, I'd like to powder-coat my valve cover bright yellow, but I dont know what it is made of. I mean, when you knock it with a wrench or somethin' it doesn't sound like anything metallic, and if you dont know you can only powder-coat metal (aluminum, cast-iron, etc.). Can someone please help me out with the 'material' the valve cover is made out of?
Thanks,
Matt
