UPP Slickness

Well I decided to let my cousin use some of my UPP. He has 3 layers on his truck and doesnt want to top it.

He was wandering how long this slickness will stay and what is a estimate of longevity of it with 2 washes a week using Megs Gold Class wash and Megs Final Detail after washing. I couldnt help him out as when I used it I topped mine after 3 layers.

With washing with Platinum (4 Star) car wash, Qd`ing with 4 Star Qd once or twice a week, , I kept my "outdoor" vehicle good for a few months...But most of the time I didn`t wait, after a month I just layer`d it again, I think he depends if its an garage queen or always outdoors..tooo...
