You ask a good question and this was the original purpose I wrote an article on MOL called,
What it means to remove a scratch out of anything
I tried to re-write it here,
What it means to remove swirls, scratches and water spots out of automotive clear coats
Only in the above article I limited it to car paint. In the original article it talked about removing scratches out of anything.
I can't simply copy and paste what I've written on MOL over here as that's both plagiarism, (in a way although I'm plagiarizing myself), and it would also be copyright infringement, which would be wrong.
The problem I have is once I've written and article, I find it incredibly difficult to re-write using different words while still capturing all the ideas. Ugh... my problem...
Anyway, the problem with removing scratches and scuffs out of "things" is that in order to remove a scratch out of something you actually don't remove the scratch, you remove material surrounding the scratch.
Does that make sense?
Here's the problem...
Some things, and in this case the word "things" means either a material or a coating, now follow me.... some things don't lend themselves well to being abraded with the end-result looking good or original.
You can abrade chrome with some sand paper and remove small scratches but you replace the original scratches with new scratches. That's because chrome, (a coating), doesn't lend itself well to being abraded with end result looking good or looking original.
That's the problem that you run into with most chrome plastic.
