Redoing peeling Red Max Pro on 2001 National DP

This spring when I had the time I gave MH a good scrubbing after taking a real beating this winter. Had a lot of black streaks on corners and the rear cap that faces south while parked along side garage need some special care. Since I didn't have any black streak spray remover which has always worked good without having any effect on RMP I used some Mean Green. BIG mistake. Where it ran down sides it took off RMP and it's real noticible.
