I think it should hold up just fine. After three seasons on my Rearwin Speedster, the paint on the bottom side of the wheel pants isnt even beginning to show signs of wear, and they rub on the grass. Ive tried KK, and had no problems with it, but since trying Nelsons, i never saw any reason to spend the extra on anything else. AND, its almost oderless. Can spray in the house and the wife dont even know. Lol.
