Go buy some high-build fast drying primer and some satin black paint and some Krylon fusion for the windshield lock strips. Take a quick 150 or 180 to the trim before priming to get any rough spots. Wipe with acetone or painting prep. Prime. Wait. Paint. Wait. Paint again and you should be done. In the meantime, paint the lock strip you removed and let it dry before trying to get it back in. Pray to the god of German cars and try to get the strip in without the proper tools without forcing it (too much) or you can crack your glass. Good luck.
