Works fuckin awesome!!
All you need to remember is,your topsheets will bubble a bit, if it gets worst then say 2 square inches, stop. Me and my buddy did them and we both had bubbling and they turned out fine. But he had let the heat gun sit on his one ski a little too long and it bubbled like crazy, and in the end the ski snapped hahaha, but anyway just do it and have fun, but be careful.
