Yeah - powder coating is sort of size fits all, at least around Portland. Take them 2 pieces...$150. Take them 20 pieces...$200.
Something that also works well if you’re doing a restoration is that you can also take things in and just have them sandblasted along with everything you’re getting powder coated essentially for free. This is what I did with a few under hood parts that I will rattle can or POR.
