Paint removal from lexan shell !!!!

[Dkfream]

Hi guys it's a long shot but here goes, painted a 1/10 lexan buggy shell and used the wrong paint type, I used tamiya TS paint, needless to say after a few days it all started falling off in places, is there anything I could use to remove the rest of the paint so I could repaint with the correct paint as it's a shame as the shell is brand new or do I just throw it away !!!!

Any ideas would be much appreciated
