I have both the Optimum spray wax and Pinnacle Souveran spray wax and have used each more than one or two times. Pinnacle supposedly improved its formula by adding more polymers but don't know if it is as durible as Otimum? I never let a car of mine sit with one or the other on it long enough to find out. However...I have found that unless you are careful, the Optimum will streak. On the other hand, I have had no streaking problems with the Pinnacle. I heard one time that it's because the Optimum has more polymers? Just seems strange to me that with all the hype, Optimum would want to improve their mix so there isn't any streaking. I use the Pinnacle mostly because of the non streaking properties.
