Collinite 915 Vs. 845. How do these waxes compare as far as looks go? I know 845 will be easier to apply, but how are the looks compared to 915. I know proper prep is the key to the perfect shine, I would just like to know how these compare. Also, how does Meguires #26 compare in the looks department? My car is black, but I would be using them on all different colors. Feed back please Thanks for your time, have a great day!
