Check out some of my details in my forum, you will notice that EVERY seal/doorjamb/light/etc is taped up. this is completely neccesary to make sure you dont touch anything your not supposed to and possibly burn it with the buffer. I spend sometimes half hour-to one hour just prepping the car with painters tape before i even touch the car with a buffer. I also found it a little funny that he only taped up the side windows???
