AFTER THE SPRING RAINY SEASON IS OVER THIS IS THE BEST TREATMENT TO USE AS A BASE FOR MOST DIRT TRACKS. USUALLY USED ON THE OUTSIDE BUT CAN BE USED INSIDE THE TIRE. WILL DROP THE HARDNESS OF THE TIRE WHEN COLD BETWEEN 5-25 POINTS DEPENDING ON THE NUMBER OF COATS, AVERAGE OF 10 POINTS. GREAT ON DIRT AND ASPHALT TRACKS.
