The problem you face with spray on sunscreen is generally coverage. Are you getting enough on every exposed bit of skin? Is it rubbing in where it's sprayed, or just getting rubbed around?
With this Up & Up sunscreen, we've never had to worry about it. My wife and I are both pasty and incapable of tanning, and it seems most of our kids have suffered the same fate. But a quick spray of this sunscreen has always managed to adequately protect us all. Nobody has ever come home burned when we've used this sunscreen.
Our most common use is visiting the zoo and other outdoor attractions, where we tend to get sweaty and spend long hours exposed. But this stuff has always served us all day long. Our zoo even has a splash pad where our kids cool off, and the sunscreen has always held on, no matter how wet they get.
One final plus is that compared to most sunscreens, spray on our otherwise, my wife and I agree that this Up & Up sunscreen feels less greasy. That's always a bonus, since nobody wants to be greasy all day.
The only drawback is that with so many people to cover, the can doesn't seem to last very long. A larger can would seal the deal, and we'd never buy another brand again.
