just curious why all waxes says not to wax on hot surfaces or in direct sunlight...what happens when u wax on a hot surface?

 

Well, I know with Zaino, is that it will dry to quickly to effectively spread it, thus you get blotches.

 

Most waxes contain solvents that naturally evaporate after you apply the wax. This helps you identify when the wax needs to be removed from the surface. In normal (cool) conditions, the wax is allowed to dry naturally. However, when you wax in the sun, the heat causes rapid evaporation of the solvents and causes the wax to harden too fast on the surface, sort of like baking it on the paint. If you've waxed in the sun with a product that says not to, you'll know that it would take a jackhammer to remove the stuff. Not all waxes work like this though. Some, like Zaino, can also be used in the sun without any major problems. Actually, when I'm in a hurry, sometimes I'll apply the Zaino in the (shady) garage, and back the car out in the sun to let the Z dry quickly. The Z still comes off very easily. Basically, if the product you use says don't apply in the sun, by all means, don't, or you'll just cause yourself more headaches...

My $.02...
