Yeah the backer can change the color of the outcome, so if you want a lighter color use silver as the final coat. Whereas if you want darker use black as you backer or final coat.If it's a light colour, then 1, 2, or 3, I follow with a light coat of black, white, or silver as backing. Be careful of the backing colour, it can make a difference in the final pigment.
If it a transparent colour, 1 or 2 coats of the base, then silver or gold if going for metal flake . Not sure what happens if a solid colour is used to back transparent paint. Just don't go too thick on that 1st and 2nd coat, it may not look like it's covering, but once the backer goes on, wow, it shows.
Yeah, me too, good advice. Just haven't actually painted in a while, but yeah, lightly shoot those nooks and crannies so you don't drown the finish later in that same coat.1st coat - I always try to hit the hard to get to areas first, then give everything a very light coat.
