Fill in deep scratch - paint on keyboard's scratches

Hello all,

unfortunately, my back bag fell down on the floor, and my MBP was inside. There is now a kinda deep scratch on a corner of the frame (as you can see in the photo). Is there any way to fill it?

Another problem is that I also have scratches on the keyboard frame around the "R" key and I would also like to fix it.

It may sound that the whole thing is not a big deal, but I always try to keep my phone, mac, etc. free of any sort of damages. The scratches on the key itself are not bothering me.

Thank you all in advance
