While doing lots of surfing, we learned from our surfing instructors that "Baby Bum Cream" (zincofax) is a cheap and better alternative to sunscreen lotion for extended time in the sun and water such as surfing and sailing... we tested it and it works great and protects really well. As an FYI, it's so good that it requires a bit more rubbing to come off...and your faces ends up smelling funny...like a baby's bum!
