keeping original paint bumper fillers black

[GSX-PKV]

My car has it's original paint and it still looks pretty nice but the black bumper fillers often look "chalky". I can make them black again using spray detailer/wax but in a week, they begin to look worse again. Is there any product or trick to keeping these black? Thanks for any tips. Paul

Had the same problem and couldn't find an answer. No matter what product I used it got to the point where they would haze over less than a day after buffing them. I took them off and had them stripped, painted, and cleared, Over a year later and no hazing.

Thanks for the input. This seems like the only way to solve this problem.
