Works much better than the original applicator which left streaks and overlaps
Works much better than the original applicator which left streaks and overlaps. Much easier to use on contours and crevices.

Game Changer!
So much better than the applicators. Easier to get nice even application on RVs. Does much better getting around the awning poles and different covers.
