Is the part you are trying to powder coat made of aluminum? If so, the best thing for you to do is polish the aluminum or at least brush it up. The anodized pieces I have seen usually have a brushed aluminum look to them, so it would save you the time of polishing the pieces first. Are you appying the blue powder on top of the chrome powder when the piece is still hot? That is a big problem that people do with this process. The powder will adhere better, but in varying thicknesses as you said. You should apply the powders on a cold piece, or at least under 100 degrees, so the powder does not melt when applied by the gun. Doing the process as you are saying here is one of experience, after a while and trial and error you will figure it out. If you have any questions, email me or hit me up here.
