i don't have any issues with tire fling using the armor all, rain or shine, it sticks real well. I might give the stuff your talking about (poorboys) a try as well cause I like really shiny tires. I use the areosol cause it's easier, I have bad knees and it's difficult for me to spend the extra time to wipe on/wipe off, plus I always have a hard time getting an even shine when I have to wipe it on and off.
