No. That would be a disaster trying to be certain you got it on perfectly at the start and ended up precise on all corners / turns by the end. The glue/adhesive on the film is crazy strong; you wouldn't get it off w/o damaging it. Simply apply and then take a blade to the edges along the chassis and you're done. It's quite easy that way to be honest.
