From German machine manufacturer Martin comes the Speed 20/10, a rollable spray station for varnishing. The one-meter by two-meter surface is covered with a roll of ordinary, cheap packaging paper, which varnish won't stick to; so when spraying your piece, there's no need to mask the underside. And it has a couple of other cool tricks, watch the vid:

What you might not be able to see in the vid is that it's foot-pedal controlled; tap one pedal to get those two rollers to pop up, so you can lift your piece away from the sides, or you can hit the other foot pedal to either advance to a clean sheet, or roll smaller pieces off of the surface and into your waiting hands. The action requires an air compressor, being all-pneumatic; they don't want any electricity jumping around, the rep explained, if folks are spraying explosive substances.
