Finished putting 3 coats of Forever Black on all the trim including the very faded piece right below the winshield. Washing the trim is key, as I got lazy and didn't wash the windshield piece and it didn't turn as black. I had streaking along the wheel arches but the front and rear bumpers did not. Not sure why. Also, the below door trim came out perfect without streaks. I'll try to post a picture soon but am impressed with the results. Another tip, we had a hard rain yesterday and I drove home from work through it. When I got home I took a towel and wiped off the trim, especially ******* the wheel arches. This has reduced the streaking by 75%. So I guess if you end up with streaks a little water and buffing with a towel or terry cloth fixes it. I recommend this product.
