Scratches

You can sand it down to expose the paint (just on the chipped area)

Then you could keep adding layers and gently wet sanding them out. (Over and over again)

Then when your satisfied with the final results, you can buff and polish it out.

Won't be 100% fix but will look a lot better then just touch up paint blob

If there past the clear not much you can do really just touch up paint. Wet sanding isn't going to do anything if its past the clear and and down to primer.
