Guys I managed to put 5 coats of Z2 pro/EFX since last Thuesday. Unfortunatelly, when I drove the car out, it rained after 20 miles (kind of quick showing off the shine). Time for a wash. I did not order the Z7. The question is.......if I use other high quality shampoo such as Sonus, Sonax, P21s or Poorboys SSS and then continue adding more Z2 pro (my latest addiction
). Are these shampoo okay to use without jeopardize bonding issue?
