Jumping in, hope I am not out of place:
We use the continuous spray regularly, it's the only thing the boys will use. It's a very light aerosol mist that covers evenly. It's kind of a stiff feeling when it dries on the skin, DD HATES it. The boys like that it goes on clear in one shot. It lasts as long as any typical sunscreen. If you sweat a lot or are in the water, it is best to keep reapplying it. It's better to spray it on dry skin than wet so it adheres. The biggest downfall to using it is that there's not as much in the can as you think. I will probably bring two or three cans with me so we don't run out. Wal Mart has it for under $7. a can. The Banana Boat spray isn't the same as the Coppertone. It's not a clear aerosol, it's like a white creamy spray. We prefer the Coppertone. If you have any other questions, ask away. We swear by the stuff!
ETA: I wil still bring traditional lotion for their faces.
