You are probably applying too much of it. It takes very little (bottle recommends two sprays per body panel) to work. If you put too much it will streak. It tells you on the bottle if that happens, take a damp microfiber towel and run over it and then buff it. This will take care of the streak. A little goes a long way with this stuff and it's very easy to think you don't have enough on an area and apply too much.What am I doing wrong??? I’ve never been able to use the Turtile Wax Ceramic Spray Coating without getting horrible streaks that I struggle to remove. I’m doing everything by hand - no DAS polisher. I always have to go back and fix it using Mother’s spray wax which has never left any streaks for me.
