My process was wash, Clay, SSR1, Ex-p x 2 (24 hours apart). Wait 2 weeks. Souveran.
This was the first wash since the wax. About 2 weeks after Souveran. No other QD was used. The car was medium dirty, but not too bad. The car is black so it shows everything. The hood was the only place I noticed the streaking. And now (a few days later) the streaks have a slight whitesh haze to them. This suggests to me, that maybe there is in fact wax in the streaks. Is it possible that something in the dust or dirt being removed may have interacted with the Souveran and removed some of it? Maybe the car was a little too dirty for the S&W wash. I didn't think so at the time.
I apologize for leading this thread off of the original subject awhile back.
