If you spray polyurethane and wait 2 hours between coats, what happens to the spraygun ? Do you clean it or leave as is ?

I stick mine in the beer fridge in the shop and that slows down the drying process. Keeps the poly from setting up.

I was watching an Apollo HVLP demo at the Woodworking show a few years back and the guy was spraying oil based varnish. Someone asked him that very question and he replied he didn’t clean the gun at all for the entire weekend until the show ended. I don’t spray oil based varnish, but I do brush and wipe a lot, and do what Joel suggested, I put my brushes (wrapped in a sandwich bag) and wiping pads in the fridge. The cooler temps really slow down the curing process.

If there’s a long time between spraying, I wipe the spray nozzle and then stick a bit of tape on the nozzle. Works fine.
