Just coated my black car with Wolfgang Spray Ceramic Coating after 2-Step correction and prep with Wolfgang Perfect Finish. I backed the car out into the Sun for final walk-around and catching any haze or high spots. Extremely pleased with the results. So, is there any advantage to applying a second coat of the WG Spray Ceramic Coating? Car is back in the garage and is as clean as it will ever be if a second application is a good idea.
