“We are trying to go to a powder coat on an extruded aluminum piece. We are coating it with a textured metallic aluminum colored finish. The problem we are having is the finish has a waviness to it …it goes from a light shade to a darker shade throughout the part. Also the texturing is not consistent and is blotchy. Are these problems normal.”
