I've been using rattle can paint to spray 2D cutouts. It seems to be the best option for my needs. I am concerned, though, about the paint sticking to the cardboard in shipping. We've had a really damp week here, and I am concerned that the paint may not have fully cured. It feels dry.
This may be one of those things where I am being overt paranoid, but I wanted to play it safe and ask if there was anything that I could use to wrap the piece that would add some insurance to prevent sticking? Wax paper, foil, cloth, etc?
