ABSTRACT:
A clear resin protective coating is applied to a picture by spreading liquid resin over the picture surface from one edge using a spreader sheet under tension which is carried by a frame hinged parallel to one edge of the picture, so that a `wedge` of resin is advanced over the picture surface as the frame is lowered, forming upon curing a clear protective layer.
