I have been spraying several pieces using a duplicolor metallic black perfect match rattle can. I'm having trouble getting a nice smooth final coat on without getting these "flat" spots all over. Maybe this is what is called "blush"? (The majority of the coat is nice and glossy and shows a reflection, these spots are like a matte finish....dull with no shine whatsoever). The paint goes on fine, but about 30 seconds later as it dries the spots emerge.
My process is to get several coats of color on the part and let it dry. Then wetsand all the orange peel off until the part is smooth. The next day I clean it again, let it dry, then spray a final wet coat of color (the can is warmed with hot water for a better spray). But usually I get these flat spots. After several attempts at this I have gotten most of my parts done and they look good. I just tried finishing my last part and I got these spots again, so I'll be driving across town to get more sandpaper and another can of paint. FYI, the outside humidity was 40-45% when I sprayed.
Anyone know why this happens or how to prevent it?
