I always put a little co2 in the can when closing. eliminates the skin forming. I sorta think painting the frame for anything other than rust prevention is a waste of time. I did mine all pretty last year. When I took the box off this fall the frame looked like it had before the paint job, I'm sorry but I don't wash down there very often.
