Prep the surface like normal, and spray a light coat, and continue with 2 or more even light coats, and finally a decent final coat. It's not hard to come off, just rub your finger across it and rub. Get a piece and you can pull it off in bigger pieces. The only time you run into problems removing it is if you do a really really light coat and done. This stuff is very forgiving, not hard to apply or remove.
