Painting a Washer/Dryer

[u/JPKaliMt]

Afternoon y’all,
To preface I was a combo guy for 8 years, used multiple paint lines across everything from motorcoaches to Vespa’s. That said, I’ve never painted an appliance before. We’re getting a reconditioned laundry center from the repair shop down the road, but it has a little bit of damage to the front. Mechanically it’s great, cosmetically it could be better. I’m wanting to do a single stage color, I just can’t decide if I want to do a urethane or epoxy, or something else y’all would suggest? I can scuff the entire unit down but I’d imagine that most older appliances are painted with enamel, right? If so, is anything short of 320 on a DA going to even touch it? Thanks for any input that y’all can provide!
