I'm with wading fool, the Coppertone continuous goes on easily and works well. Just make sure you hit all areas, it has a fine mist. The only reason I stopped using it is because the smell really stays in your fishing clothes, but kids don't have to worry about that.
For me, the sun is my enemy, Irish/Scotch blood. I have found Kinesys spray. It goes on in a really fine mist, then dries dry. No oily feeling and no strong smell, and you don't break out if you use it over a long weekend of fishing. I have used all of them, the bull frog is the nastiest, but works great, and Smart Shield takes a brillo pad to get off of you after a day of fishing, lol.
