I also pick stock colors. So easy to mod or change if needed. Powder has its place, not so likely to crack and get weather under it as it is outside equipment. I see a lot of it failed. For indoor stuff often don't bother to prime, simply give it a shot to get the color on it and no one notices perfection if its masked, not over sprayed and basically the correct color if it came factory that way.
I like paint as its fast, can do it myself when I want. I do see some powder here and am actually impressed with the price, its very reasonable. Having a system, place rigged to paint helps a lot, takes a lot of the misery out of it if its easier. I keep some color in stock I use regular, where it needs to be durable I use Imron Industrial.
Last pic is simple refresh during a mod job. I mask, cover labels, don't over spray stuff that shoulnt be. Doesn't always got to be perfect but not eye catching ugly.
