What happens if you drive before 1 hr? I tend to slap on a layer of UPGP once a month or so and will often drive the short distance to work before 1 hr. I've never noticed a problem, but I'm working on my own car and am probably not the perfectionist you are.
Anyways, it's UPGP for me!

Not sure, but it says to wait an hour. Maybe it is like going into the pool right after eating?
Maybe DavidB will comment?
