Plasti-dip is probably the easiest way to go. First clean the trim. Tape off around the trim you want to paint. Overlap your tape going one direction. Either clockwise or counter clockwise but not both. (When you go to remove the tape it will all unravel in one piece this way. ) Use blue tape for automotive. Masking tapes have stronger adhesives and can be a pain to clean up. After taping off, make sure to tape newspaper around the outer side to keep overspray minimal. You don't have to, the plasti-dip rubs off but this just saves work. Spray the parts in a smooth motion with light coats. It will look bumpy but it will smooth out once it dries. If you want flat black, you're done. Peel the tape off. If you want gloss black apply plasti-dip glossifier. For a super smooth finish, use a tack cloth lightly between dry coats to remove overspray. Best part is, if you don't like it, you can peel it off and you've only spent about $15-20.
