Now this sounds interesting. I am really not trying to win any woodworking awards for this one, so a paint sounds really appealing to me.If you want a durable finish in less time consider exterior alkyd enamel house paint. (regular exterior enamel house paint, the stinky kind) The plywood floor I painted in enamel has lasted 2x as long as the varnished one. The enamel only needed two coats and it dried in less than 5 hours. It was also cheaper.
I know you're not asking me specifically but IMHO paint will hold up much better and be way easier to maintain in the process. If you have issues with checking or cracking, you'll likely end up doing a complete refinish with varnish vs a simple sand and recoat with paint and if your using ACX its almost certainly doug-fir faced so it will check no matter what you do (except maybe epoxy impregnating). If you don't really want a bright work finish, paint it - you'll be very happy you did.Now this sounds interesting.

You think paint will hold up as well as Spar varnish to straps being cranked down on it and such?
