Since I have a lot of spraying to do for my bathroom cabinets, I figured I'd better build a drying rack but didn't want to spend too much time or money. I used 3 2x4's, 6 10' pieces of 3/4" pvc pipe and some scrap plywood. The PVC seems like it will be plent strong unless the panels stick out too far. If I have any panels that large, I'll slip some 1/2" EMT inside the pvc for extra support.
