+1If it's single stage paint, you may be stuck with it. If it's basecoat/clearcoat, depending on the number of coats, you can lightly sand it and buff. Make sure you know what is on there before you try any sanding or buffing. If you told the painter this was for a track bike, chances are it may not have the best system on it if you got the work done cheap.
If you paid a lot for the work, take it back and ask them to make it right.
