stains on white M/B

[KWOLDIE]

when I detailed this M/B 2 months ago it had streak stains on the hood and trunk that I believe were caused by an automatic car wash. I washed the vehicle used a clay bar applied PB white diamond glaze then PB EX sealant with wax. 2 months later streaks have returned even though the car has been hand washed since. Any help would be greatly appreciated

I would try an AIO/cleaner wax to see it that helps even it out, or just a simple polish if you don't have an AIO.

I had a similar issue with a single stage metallic green Jeep that went Thur a automatic car wash and the strong detergents ruined the hood and other panels. It was a cheap single stage paint job but my best try was just using a one step polish like HD speed, lasted a few months but a repaint was due.

Also it's tricky with single stage paint, let alone metallic as it can cause unevenly areas due to metallic.
