I always primer and sealer with a grey color.Sealing with a color that is close to what you are spraying does not always cover faster,its something about the neutral color of grey that covers faster,Jim might be better to explain this?For my personal pumps I found a brand called american finishes,cheapest paint I have ever found and lays down slicker than sikkins.About 40 a gallon and they have a very bright red.
