Dear All,

I'm building a custodesarmy using the new grey knight rules. Its an idea Ive had for awhile so Ive pretty much assembled all the bits I'll ever need.
My question is what has everyone's experience been with painting them or gold armored marines in general?
In particular I was curious about what color they should be primed. Ive heard and read numerous opinions ranging from army painter standard brown, krylon ruddy brown to generic black.
