Although it sounds stupid its true.

Wax will help your car go faster by defeating wind resistance and frictional drag. WW2 P47s and P51-Ds used wax on the entire body and wings of the plane and reached speeds in excess of 460mph. Im not sure but I believe they said 10mph was accounted to waxing and having clean air surfaces. maybe its good for .15 mph in the 1/4 ??
