how do I finish the spark plug heat shields om my 65 malibu SS, with 283, 195 hp. I will bead blast them and expect to paint them. but what color, what paint, etc.

They were plated originally in a silver color, if you want to duplicate it without plating use Martin Senior High Temp silver, looks good and will hold up. Its a little brighter than most silvers almost like a chrome paint.
