It's very important when purchasing products to actually see what your car care methodology is. For example, if you're going to wax once a month, a good spray wax will easily last that duration. However if you're only going to wax once every 6 months, it would be better to look for a good paste wax such as collinite or maybe even a liquid sealant.

Also you have to consider that spray waxes have come a very long way, there are spray type waxes out there that was made to compete directly with paste type waxes. For example, Optimum Car Wax has been claimed to include UV absorbers / protection.

Spray waxes are easily applied and most spray type waxes are very slick which is good - and it stands the reason why detailers the world over love using spray waxes as a type of drying aid. Using a drying aid is also a good idea as it will help prevent the swirl type damage on your car.

So to surmise, methodology and technique is important. Happy detailing!
