White spirit.
hairdryer can melt the paint also.
Start at the top of the PF while its still in the game and on an incline, put some white spirit under the lip of the mylar and pull back slightly.. it will just lift off with no effort. Then apply again etc all the way down the PF.
Plenty of residue will be left and will need elbow grease and a cloth to remove, but white spirit will seperate the glue from the plastic sheeting
