Surfing Waves

Hi , I'm off to Sri Lanka in a couple of weeks and just tried reordering my trusty Island Tribe sunscreen gel...but...everywhere in the UK
seems to have sold out.
Does anyone know of any alternatives that are as good. I tried Panama Jack once and it just ran into my eyes and stung like a squillion bees.
So, I'm looking for an absorbed gel with 50 factor protection that genuinely works in warm salt water.

Any clues??

dont know gel alternatives, but invisible zinc (or just normal zinc) is good option as it doesnt run into your eyes. I also use Island Tribe and prefer it over invisible zinc, but the zinc does just as good a job. Just a bit less 'nice' to work with
