I'm thinking that applying UPP after DACP might have been a mistake. After a month(almost to the day), the UPP was completely gone except for the rocker panels and the area just above them. The only other reason i can think of would be the NXT wash that i use, but i really doubt that it would be detrimental to UPP and be fine with every other type of wax that i have used.
Is using nothing between DACP and UPP the reason for the durability issues?
