I prime it with plastic primer, give the body of the blaster a good coat of silver, and the scope was undercoated in gold. This one, I gave it a coat of hammered black and finally coated the entire blaster with flat black.
After it cured a day, I scuffed it good with scotch brite pads and scratched it with and exacto knife. Also, for a better showing of the undercoats, I masked off areas and lightly dusted with gold and silver again. I let that flash a bit and unmasked the entire blaster, then dusted the whole thing again with flat black.
Next day, I lightly scuffed the blaster with scotch brite again. I also highlighted the lettering on the scope with white.
