The term is Clear Coat.
It may be difficult to repair depending on how much of it is peeling off. The trick will be to feather the edge that is peeling off so that a new coat can be sprayed and blend into the old. The clear coat can be sanded with a very fine sandpaper but you have to be careful not to sand through the paint.
The clear coat will be a 2 part mix, one will be a hardener. If done correctly the new clear coat will essentially dissolve and melt into the old and when it dries you shouldn't be able to see the difference. To make it real smooth and shiny you may have to do some light sanding and buffing.
Here is a Youtube video on it, do some searches and you should be able to find all you need to understand how to fix.
