Replying to Look Pivot 18 paint chipping

I have a pair of white 2018 Look Pivot 18s that I love dearly. I bought them used and they had some minor chips on the heel piece. Over the last month of skiing hard those chips have gotten really nasty.

Is there something I could do to stop or repair this issue because I would like to use these on another pair of skis and they’re functionally fine but I’d rather them look good. Maybe white nail polish or something like that?

thanks!
