Powder coating is an industrial process. Powders for powder coating are optimised for different applications, whether that be long term abrasion resistance, uniformity, UV exposure, sticking to rough surfaces, hiding surface defects, etc. The harbor freight powders are designed to hide surface defects on rough parts. For that purpose, they work well. For the purpose of preserving detail with high uniformity, they are the wrong kind of powder. Mixing powders probably is a bad idea more often than not, if you aren't considering what the powders are intended to do.
