Nah, in a perfect world you would have had the rusted panels completely removed
In the future, put that POR on with a disposable foam brush and it doesn't leave brush marks and you merely pitch the brush when you're done.
If you're just trying to cover up brush marks and it were me, I'd get some 2k glazing putty and it should fill in the brush marks nicely. Sand it down with 180 or 220 and almost all the putty will sand off except for where it filled in the brush marks.
