well i bought back to black 2 days ago, right in the parking lot i applied it to my plastic bed rail covers, looked amazing, works like a charm, drive it home, rained the next day, went out today and there was none of this streaking you few folks are talking about...? so i dont know what the deal is with that, but i dont have that issue. used it on the trim around windows, and bumpers front and back this morning, rained this afternoon, no streaking either.
so id recommend mothers back to black. no streaking or any ill effects for me!
