I've no clue how my bro let this happen to his car up he somehow got a scratch on his front right quarter panel. It looks like a keyed scratch not too deep. Any tips on how to fix it. ?????Touch up piant????

 

I wouldn't do the touchup paint if it is a very big area that you would have to cover or if it is in a highly visible spot. In my experience it always stuck out like a sore thumb. If it isn't very deep wh try some of the GSX27 (or what ever its called) scratch remover. I have tried it with limited success. you can get it at Kmart.

 

If it is not that deep then maybe only the clear coat was scratched. If so then it real easy, all you have to do is get some clear coat filler like 3mm or some other brand at your local auto accessories store. All you have to do is rub it in and your done. I have used the brand 3mm on some scratches and it worked great.
