Step one will be securing two sheets of hardboard to the shed outside, a more preservable canvas than the current choice of the side of the shed itself.
Step two is priming the surface, and where I'm hoping for help from the group mind. My nascent thought is to roller on some good quality exterior white. But will that be suffient? Should I use a primer first? Will exterior paint make the spray can paint bead up? Stuff like that.
I know we will learn by doing anyway, but it would be great to skip some of those particular learning experiences.
