Thanks again, everybody !
Larry, the graphics are on order. They incorporate some of your suggestions.
Dave, I sprayed Minwax Polyurethane to clear coat an Old Timer, a few years back. The polyurethane showed no ill effects from glow fuel. I believe the stuff to be at least fuel resistant.
Keep in mind that this is the oil based polyurethane, not the waterborne polycryllic. The water based stuff will turn to goo when fuel residue hits it.
