We have 2 different waxs on hand, Jescar/Menzerna Color Lock and Chemical Guys Butter Wet Wax. During the summer I like to use Menzerna. It cures quick and last several months in the Texas heat. During cooler weather I use Butter Wet Wax as it cures quick in the cold and last a long time during the cooler weather. However I try to get everyone to get there cars waxed before the cooler weather that way I can use Menzerna that way there car will make it thru the winter and most of the summer with this wax. I do use Butter Wet Wax on cars that have a lot of swirl marks or dead paint as it works well as a all in one paint correction. So it just depends on the car and the conditions on witch wax we use.
