I removed my Mylar very easily. The worst paint loss was on raised inserts (decals available) and by yagof's face. And by the pop bumper. I tried freeze spray for a bit, then tried "goo gone" finally I just pulled it back slowly taking care as I went.
After the Mylar was removed I used multiple coats of goo gone to remove the glue. The goo gone needs to sit for 10 min befor you take it off. *dont confuse it for goof off, that removes paint*. And the final bits of glue I just rubbed off with my fingers until it balled up and could be picked off.
I had to touch up the paint on the faces, and around the pop bumper.
