Paint does go through a 'curing' process, of sorts. Even though is isn't 'wet', it is giving off vapors. Probably not after it leaves Detroit any more (or Viet Nam), but even if it is, I don't think it will cause a problem with the paint. It could possibly make for a waste of waxing time - here's how...

Notice how your spray paint can says "Re-coat within one hour, or after 24 hours".

Within one hour, the second coat applied will allow the vapors from the first coat to escape. The first and second coats mix - sort of, and vapors from both coats escape simultaneously.

During the 24 hour period, a second coat applied during this time will stop the first layer's vapors from escaping, and the vapors will be trapped under the second layer. Bonding of the second layer will be interfered with, and the curing of the first layer/coat won't be right either.

After the first coat's 24 hour curing period, no more vapors come off of the first coat, and you can re-coat.

Factory paint has higher quality/curing period (usually it has epoxy hardeners also), but I don't think even the clear coat has a one-year cure period. Whatever the cure period, the wax would not cause the same problem as the second coat of spray paint, because it doesn't chemically bond the same way as a second paint layer.

 

gulf lubricants makes lot of accessories for cars now a days. This spray i think is 400 ml and if you use once a week, should come for at least two months; there are also other polishes available in the market such as formula one, but this is the only polish available in spray form;
