I plan on using Wolfgang Deep Gloss Paint Sealant and am noticing some scratches from the snow brush on the black plastic parts of the side mirror pods.

A detailer mentioned that those scratches are there to stay. They aren't bad but I can see them from the driver's seat. I just wonder if Back to Black or something similar will cover over the scratches.

And then since I plan on using the paint sealant on the black trim as well, can I use the sealant over whatever I used on the black trim first?
