Finding aids to support someone with cerebral palsy in his workshop classes.

Hi, I have a student (16) in college with cerebral palsy - right hemiplegia.  His right hand, moves outwards and he has very little grip with right hand.  He is an automotive student.  The issue we are having is he is unable to hold masking tape and tear a stripe off to put down on the car window, for his practical lessons.  He currently does it with support from his teacher or support worker but we want him to independently do it himself.  I am wondering if you know of any aids to support him in his workshop classes?  As someone with cerebral palsy myself, I want to to do anything I can to find a solution.  Any advice would be greatly appreciated.
