I've never done volumes of painted base. I'm thinking it would be good, quality wise, to put the paint on the material with an airless, then give it a quick back roll.Give me a brush… and I’m on no rush
I've done that a couple of times with some polyurethane on stained wood and it works really well.
Using a roller or dipping a brush into paint and applying it is ridiculous compared with spraying on an even amount and then back rolling or back brushing. It's still slower than simply spraying it but it works the paint into the wood surface.
It's just a theory of mine and I'm full of them, full of it, .......whatever.
