I have found that before you use a machine to cut and buff the paint take some 3M masking tape "the green tape works the best" and tape around all the metal body panels including the window trim and anything else close to the area to be cut or buffed. By doing so you will help reduce the chance of burning the edges of the paint and damaging the trim around the area being cut or buffed. The bounes to this is that when you are done you won't have all that compound caked in the cracks around the hood,fenders and trim ect. Remember to always wash hand wash between using differend grades of compounds. As you keep using lighter compounds you want to remove all the residue from the last on used. I think I just told you what everyone else did but if there is anything you can use here that can help you its worth the post.
