So... yeah, there's AIO + SG x2 on my car right now. Tomorrow, rather than layer SG further, I'm going to top with P21S. In a few days, I'm going to wash, do everything else (wheel wells, engine, interior, ...), and use P21S one more time. And then school starts again on the seventh.
So then what? Do I just do my weekly washes, monthly P21S applications, and then start w/ AIO again in a few months or so?
