Why do you have to wait to wax a car with a new paint job?

Waiting to Wax a New CarBy waxing a new paint finish you are trapping the solvents that have not yet evaporated. Trapping the solvents can lead to blistering, refered to as "Solvent Popping" Although a paint finish may dry to the touch in a short time, the paint does not reach its complete hardness until all solvents have escaped. For the first polishing, I recommend using a polish that does not contain wax or silicones. These products are referred to in the industry as "Body Shop Safe". 3M Imperial Hand Glaze is good product for this but requires a lot of elbow grease. It hides all swirls, rags marks, etc, but will not trap solvents.
