I used stucco merely as a comparison. its some variety of industrial coating. they built cranes where the forklift came from. as for pressure washing.... its already in pieces on the shop floor. the mast is fully dis-assembled now and ready to head off for blasting and priming. actually pretty simple to remove the mast once I figured out how it was attached. kind of a neat design actually. which by the way I have read is a patented design.
