What's that smell?
The streaking was very faint and, like I said, I used UPP on other parts of the car and did not have any problems. I wouldn't really consider it a major issue, but it is noticible when compared side by side with EX, which wipes off without a trace of streaking. I have found that many products leave a few little "artifacts" behind that need to be dealt with with a spritz of QD. Just so happens that EX is in the minority in that it removes so cleanly.
