Walgreens put out a 70spf spray that is cheap and works well. I was at a youth camp for teens through church and used it and it held up through swimming and I didn't get burned. It did not leave any kind of greasy or hard surface, but soaked in. I don't know if the spf is high enough for you, but the price is reasonable and itis a pretty good spray. Even my vitiligo, which always burns, didnot get any pink at all. I was very impressed.
