I find that the best way to treat the look of your car is to.........(how does the old saying go?) get out of it exactly what you put into it. The difference between the glossiness of liquid and hard waxes is somewhat circumstantial. What makes a car shiny? Reflectivity and surface quality, right? The smoother the surfaces of a vehicle are, the more light it is going to reflect, therefore the car looks much more shiny. Example: If it is the middle of the summer and you know that the next day is going to be a scorcher, wax the car the night before. The logic behind this is that after you wax a car there are still small pieces of wax that sit on the surface. These particles break up the surface and reflect light in different directions. When the car sits in the hot sun the day after you waxed it, these particles melt down and become flat with the surface, reflecting light in one direction. Make sense? Bottom line: the difference in gloss between the two types of wax is really marginal. It is the durability that makes the difference. Hard waxes last much longer than liquid waxes and are much more resilient to the elements. Also remember to clean and polish your car in the proper order. (debug/detar, wash, rinse, clay, rinse, dry, compound/scratch remove (if needed), polish, wax/seal).
