guys, do i need to have wax applied (after car wash) first on the car before i could start applying QD in between washes? Pwede na ba yung Eagle One WAUD lang ang gagamitin ko?

Problema ko kasi is that i can only have my car washed sa mga neighborhood carwash, and can only do "dry" cleaning at home. Bawal po kasi mag linis ng car using water sa basment parking area. That is why i thought that applying QD and EO WAUD would be the best para sa situation ko.
