I'd post a pic, but the results are hard to see in them.
I used a metallic rattle can from about 2 ft back between every second layer, working with the original TremClad method of 2 coats, wetsand, 2 coats.
I applied 1 coat, sprayed lightly from a distance, not enough to add the silver color, just heavy enough to let the metallic show, then applied the second coat. I admit it's a bit uneven in spots, but overall I was happy with the results.
Try to find an enamel metallic spray rather than a lacquer base. I used a silver metallic with green.
I did post a couple of pics on pg 71 in reply to Radio Joe's question about two tone work.
