i use to do the tech wax axle prep, and found out that most of the multi layer multi different waxes , 25 step plan to a faster car was at BEST just a little slower than using the DD4H method. problem is that all the different steps cost more and if you mess up just one then the whole prep is junk. not saying there are not guys that do the complicated method, just i found it wasnt for me and soon after learning the DD method i found speed.( at least in one class )
