I've always had success using a hair dryer, a microfiber cloth, WD-40 and elbow grease. Be sure to throughly wash and wax the area after you have removed all the adhesive residue

On a bit of a side note, please be careful of which forum you are starting new threads in. This thread really belongs in the Exterior Forum, not the For Sale/Wanted Forum. I reported two other threads you made in the For Sale/Wanted forum because they should have been posted in other forums. You will not get in trouble for this, reporting a thread just means a mod will eventually move it to the correct forum. Posting in the correct forum helps keep the forum neat and tidy and also greatly increases the chance you will get more helpful responses. Again, I'm not trying to be mean or anything, just giving you a friendly heads up
