I rattle-canned the black fibreglass bumpers on my old '88 GL, but I painted 
them to match the later silver-grey versions. I used cast iron finish engine 
block paint, with a 3" strip of black marine molding tape down the center 
hump. It's still holding up quite well over six years later (sold the van to 
my BIL).
