How's the marker/grime removal going? If the spray paint is acrylic/latex, try a water wet cloth with a little bit of turpentine, that's how I used to remove Stabillo grease pencil layout line residue off a ll kinds of paint in the shop. Sometimes Pledge or the like works wonders for removing grime.
A little nose grease wiped with a clean rag rarely hurts and ofttimes helps as well. ;D
