Oc, I'll answer some of the questions and others will chime in. #1 As far as I'm concerned, powder paint is the best of both worlds. It's durabilty is outstanding and you can apply multiple colors to a jig once you practice for awhile. I use many different manufacturers of powder paint, and have never found one that is not durable, providing you bake your jigs. There is no such thing as best. Many guys use Pro-tec, although it is good paint it is in my opinion very expensive. I won't pay $20/lb when I can get it for $7, unless it is an exotic powder or custom made for me. I have done a lot of study and triall and error on powder paints, and unless you buy some stuff that has been mis-handled they all are good. So I go to the alternative powders. Once you get to learn how to use them they all work fine and are durable. #2 Non-fishing powder paint. I'm assuming you are referring to brands that are not elaborate and don't say made for jigs. All these powders are fine and can be used for painting jigs. #3 When you mix two colors of powder paint, you will not get a true color. So lets say you mix blue and yellow. The pure color would be green. However when powder paint is made the colors are made in the blend. So when you mix it yourself, you will get a shade of green, however it will not be pure but a blend. This is not like mixing house paint in the liquid form. #4 I do not use it and I personally don't think it is worth the money. I can powder paint anything in the world with the powder paint I have and I think my jigs look pretty good. The key is to learn how to use powder paint to your fullest potential. Learn how to blend, shade, heat, reheat and everything else. Powder paint is just that powder paint. It is a tool, how you use it to create your masterpieces is up to you. Take a look at my avatar, that spinnerbait was done with powder paint. #5 I can't help you with this as I don't do this process.
