So I stole this idea from Eastwood. At their SEMA booth, they had lots of different color samples on 3×3 diamond plate pieces. It really allowed the depth of the different colors to show through. I ordered 100 3×3 pieces from http://www.diamondplatespecialties.com last night. With holes drilled, it was $48 + 8 shipping. I think it will be much better than the aluminum foil I have been using.
