The best thing to use is chrome pin striping. You can get it in 1/8 inch width at any local auto parts store. Just make sure you clean up the channel where the old chrome trim is. In other words, remove the chrome tape that is left over and make sure the channel is smooth so the tape lays smooth.
There may be some other techniques, but that one worked well for me. Good luck.
