Peck, the biggest reason to use primer over sanded painted surfaces is to provide a uniform surface to paint over. An example would be my truck. It is currently at least 5 different colors and each color would cause the paint to appear differently, especially with the first thin coats. If it was all one uniform color, the paint will cover more evenly. Also, the key is to not sand down to the base coat.



This is exactly my issue, plus some bare metal.

Thanks, I'll try the clean metal primer. I'll roll it straight also.
