Brooks Cab roof

The roof just sits on the cab and is held there by friction.  I wanted to keep the inside as clean as possible.  I printed mine using Versatile Plastic and I went with the recommended Processed finish and just white.  The finish is pebbley.  I sanded the outer surface of the roof with some 400 grit sand paper to smooth it before I primed and painted it.  I painted the outside of the roof so that the Aluminium Duct tape I use to create a lead roof look has something to stick to.  The inside was primed so that the craft paint I use to make it look like wood has something to stick to.
