Actually I'm trying to avoid brushing at all. I want to spray it to create the smoothest possible coverage. The reason I was considering a deck sealant is they soak in and brush marks are non-existent. I've used Kilz before inside of canopies and it didn't seem to level well and you could always tell it was brushed. I wonder if Kilz offers a primer in a spray can option??? I keep a gallon of their oil based and latex based on-hand for house projects, but can't recall ever seeing any Kilz products offered in a spray can.
