Do you see that baby pool? It's old and warped, but it works amazingly well for spray painting. For this particular project, I just set the board down in the pool and coated it as well as I could. When the first coat was dry, I rotated the board and sprayed the rest of it. I just kept rotating and flipping the board until it was completely coated.
I'm sure that many of you have clever solutions of your own. If so, I'd love to hear them! Leave a comment below!
