I just tipped over 10K miles, general freeway/in town, few DE's... I gave my car a nice wash and noticed, what appear to be, mini-craters in the front "bumper", just above the center fake inlet. I'm sure they are due to hitting small rocks (at speed!). My question is, ... since the bumpter material is "plastic", is there someway to smooth these things out without totally damaging the finish?

I'm not looking for concours presentation ( I should have worn a 'bra' for DE's maybe), but just trying for a bit of improvement.
I can try for some photos if this would help with responses.
Thanks in advance... D of D&D.
