I've started "skinning" the exterior of the coach. I'm using panel adhesive and screws to attach the 1/4"-thick exterior-grade plywood. To attach the radiused pieces, I started on the left side of the panel and installed screws every 5" bottom to top. Then I was able to bend the plywood and screw the other edge in place. Note the vertical blocks holding the panel flush with the bottom of the deck. These are my third and fourth hands while wrestling the panels in place.
