The bump strips on the door i would say fill them, can see any easier way of doing it, they wont need too much filler. The windows come out pretty easy with some cheese wire, there easy enough to put back in too, but like others are say u can just mask the windows up and take the door windows out. Pearls and candy paint are alot harder to work with so im told, (im just a panel beater not a painter) make sure u get a water trap for the compressor, u dont want water dripping onto your paint, also get urself a dual action sander, its alot easier than rubbing down by hand, dont rush the job, make sure everything is perfect before u start painting, the key to a good paint job is the prep work.
