Possibly the worst car wash I've ever used
I've never had a product streak and spot like this one. Followed all the directions: in the shade (on a cloudy, cool day), but I spent more than an hour rubbing out all the streaks. Once done, the coating left behind is very slippery, but the amount of work involved isn't worth it. Tried it on 2 different cars at 2 different times, and the same result on both.  It's gone in the trash.
