I have had very good results from painting the underside of the deck with POR 15. There was no paint left on the underside of my 272 when bought it, so I wire-wheeled the loose rust off, treated the bare metal with the recommended Metal Ready solution, rinsed and allowed to dry and then painted on the POR 15. That stuff is rock hard, very durable and provided a pretty slick finish when cured. I get very little accumulation of grass on the underside.
