Put down a thin strip of primer 94 around the outside perimeter of a window, let dry, then apply the perf.

I have not had any edge curling after I started doing this.

3M edgeseal around your perf is a great idea also, its like $10 and will guarantee against edge lift also.

I like the primer 94 better than the edge seal just because it makes less of a visible mess.

Primer 94 is made by 3M and is available from almost all the suppliers, usually with the "wrap" sections of the catalogs.

+1 on the Primer 94 along window edges! It has worked great for us as well and looks much cleaner than edge sealing tape in my opinion.
