I started to order some Blackfire Midnight sun spray wax but am holding off thinking about it. My concern or question is...The Midnight sun is about $23 a bottle. Meguires D-156 is about the same price for a gallon. I have used D-156 and am trying to justify spendin so much more for Midnight Sun. Has anyone tried a side by side comparison of the two or is the only difference going to be in the looks?
