Hi everyone. Recently bought and renovating a 2001 Palomino Filly. Did a cleaning to remove mildew with Star Brite and now would like to waterproof. I see lots of warnings about being careful not to use the vinyl waterproofing on canvas and vice versa, and that PUPs use all different types of materials. So very basic question, but is all the white material on this type/year of camper canvas, and the darker material vinyl (example pic below)? Also any tips for the bunk end corners, that seem to be getting extra wet when it rains. Thanks!!
