I use PPG Omni-AE MAE Acrylic Enamel, Brand Code 71973. Looks great, dries fast.
I also use rattle-can Rustoleum Professional Safety Red for some small parts first coats. Almost perfect match. I used Rustoleum Prfessional Safety Red by the gallon on a plow last year. It looked great but it took forever to dry, even with hardener and reducer.
The Straw Yellow we use is almost a prefect match as well. It is PPG Omni-AE Acrylic Enamel, Brand Code 3274. Looks great!!
