Pman1961,
Even though my tires were brand new, I cleaned the entire sidewall of the tire 3 times with Spray Nine and a stiff scrubbing brush. After using Spray Nine, rinsing with water and then drying, I used rubbing alcohol on the tire and mounting side of each Tredwear letter. If I recall correctly, Tredwear does not recommend using tire dressings on the letters so I have not used dressings on my tires since I installed the letters.
