i used "XO RUST" hunter green oil enamel on my dump. the guy at the hardware store said it was better than rusto paint. $25 a gal. painted it four years ago and still looks good and is holding well except for wear and tear. once a year i wax it with mcguires spray and wipe wax and when im done it looks as though it was just painted. dries to touch much quicker the rusto.
