I would try to put a cap on those skins if you are going to climb over them. I learned from building stockcars that a doorskin wont support any weight and will crease with the slightest sign of weight. You could rivet another piece of sheetmetal along the top edge, brake it into a u about 1 1/2" -2" wide then rivet the other side to the cage bar. Amazingly strong and no jagged edges to tear clothes. Skins looks good though...
