Not sure if your stone guards are matte black or clear. Based on the comment that they aren't yellowing I would expect clear. Clear can polished to extend their lifespan if you're comfortable with that. AMMO NYC has a video explaining the steps, but its pretty straight forward doing compound and then polishing. They can't be sanded to remove nicks or scratches though. However, that technique isn't going to work on a matte surface like the black ones I've got. He also has an instruction video on a process for the removal of PPF which could be applied to the stone guards.
