That can be harsh on your paintwork if your using acrylics. I just made sure my paint was well cured, it was about a week before I took the stuff off and cleaned the canopy with some tamiya polishing compound. It was all off in a snap! I'm going to try it again on my Lancaster glasswork and post pics
I used this stuff on a model a couple years ago and when all finished I peeled the stuff off and it left the adhesive behind. Don't recall the difficulty factor in getting that crud off, but I've never used it again and wouldn't. Look around for 'Parafilm'. It is a superior product and leaves no residue.
