I painted a lot of big trucks for the Phoenix Bekins Moving and Storage when i woreked for them as a part time mechanic. Washed them off with cleaner, sanded any rough spots, masked off stuff and sprayed them on the asphalt in front of the shop. I've used rustoleum, commercial automotive paint, enamel for painting school lockers just abaout anything that will go through a spray gun with my Home Depot 2 horse compressor since.
