I love Mothers quick detailer. I haven't come across another QD that makes the surface shine like it does and makes the surface as slipery as it does!
It does streak easily if you don't know how to apply it. If you use the mothers on a hot surface, then it'll streak easy. That is the only thing I don't like

Other QDs you can use in the sun with no problem.
You have to apply a very thin mist and then use your towel to spread it over an area quickly, and then flip to a dry side and go over the surface in fast movements. Don't use any downward pressure when buffing it off, just very quick movements with no pressure.
