Any ideas of a product that might "fill in" and add some gloss on this rubber bumper. The rest of the fiberglass body still looks new. '81 Corvette, Bowling Green urethane paint, garage kept for the 33 years I've owned it.

I "soak" Meguiars #7 into it to with no change. Carnuba zero.

Hmm...that seems like a question for Dr. G. I wonder if the Optimum Gelcoat Restorer would do anything for that? I'm presuming that's single stage, which maybe gives you a better chance than failed clear. Is the rest of the car lacquer or enamel, vs. the urethane on top of the urethane bumper? Those flexible bits always faded back then, I guess they used different paint on those pieces, whereas today I think it's the same paint. Is there an inconspicuous spot where you could try a coating or something?

You got that car when it was 10 years old?
 
You could try Cerakote. Not sure if it would work without being splotchy.

I have thought of it but I hesitate because of the splotchy result on a friends B pillar plastic covers as it aged.

It's enamel, yes, I purchased it in 1991. I looked under it and the stenciled vin number was visible and still is today on the frame. The fasteners were still showing the factory finishes.
