I can say it's the same color, but I not the same paint. I touched up a rock chip on my trim a few years ago and it surprised me that there was no primer under the black paint...just bare aluminum. If you are going to strip and repair the the windshield trim, you may want to look into an appropriate primer. I would not trust SEM trim black to stick long term on bare metal. SEM does make primers for all of tbeir paints, even etching primer. If you are not stripping the paint that and just recoating, a light sand with 600 should suffice.
