Use 3m adhesive remover if you can find it, otherwise goo-gone will work just fine. I didnt use a hairdryer when i pulled mine off, but I heard it makes it easier to remove. Prepping them, start with a low grit, then workyour way high, I used 300, then 600, then 1000. You need to scrape off all the old tape behind the mouldings and put some new double sided tape to stick them back on. Make sure youi get the tape that is designed for exterior use, otherwise your mouldings will fall off after a week.
