Will the crystal coat effect take place if I apply Wondax -1 to the car when the car is cold like during the cold winter months?
A. Basically, the resultant hard coat effect of Wondax -1 occurs independently from the heat of the sun. In the case of using the product in the winter months when the car is cold, just let it sit on the body surface for a longer period of time. The sun’s rays are what hardens the product into its strong crystal state and will improve its luster and quality as exposure to the sun increases.
