I went to the beach last weekend and used some of that spray-on sunscreen. I popped it out right when I sat down in the sun and read the back, "Apply 15 minutes before going into the sun." Alright, that's not going to happen. If it's that important, they should really put that in huge bold letters on the front. Next, it says, "Don't apply in a windy environment." There was nowhere to hide from the wind on the beach, so I stood downwind and sprayed myself. The method failed to achieve full coverage; when I take my shirt off now, it looks like I have sunburn camouflage.
