So far stioll have not matered how to prevent tire sling off. I currently have dp's gel and aa tire foam. I usually wash the very early in the morning and apply the tire dressing. Ive been using the aa foam alot more lately. Anyway I apply one coat, let it sit for at least 4 hours sometimes even more. Then if I have to go somewhere, I always wipe the tire off with a clean microfiber towel. But when I return back I always have the sling off that I have to use crystal mist to get off. It seems I have to do this at least once and then I am good. I would like to avoid this extra step. Any help would be appreciated.
