The argument made for traditional wax over spray wax generally boils down to a spray wax has less durability when compared to traditional wax. Spray wax does work, this is generally not disputed. What is disputed is for how long they work. People seem to underestimate spray wax and over estimate traditional wax. This is what I have been noticing anyway. I think that a traditional wax applied every 2-3 months is the same as a spray wax being applied with a weekly or bi-weekly wash routine with the added bonus of being a lot less work. What are your thoughts?
