As the title reads... for some reason i was getting out of my car today and noticed slight scratches on my door handle(something that 1 of my stupid friends mustve done getting out of my car ) but my question was how can i remove the scratch? Is a PC necessary for that???

 

is that real aluminum?

regardless probably use something like a very mild abrasive (ScratchX)
on a cotton pad.

 

I kept getting the same thing and finally figured what was happening. In my case, it was the seat belt hitting against the door. I'm so short I have the seat up in such a way the belt hits when I exit. I tried a million things and just gave up and bought a new trim piece. It pops off easily and installs quickly.
