I don't have any advice - but I've been looking. On a multi-day ride last year, I got 2nd degree sunburn on my shoulders, through my jersey. I put suntan lotion below the jersey and got no color whatsoever - but the sunburn on the shoulders oozed by the last day of the trip and my jersey stuck to it. The jersey had a pattern on it, so the sunburn had a pattern, too.
There was a couple on that trip that had long sleeved white coolmax shirts they wore every day. I've been looking for them, but haven't been able to find them (the shirts, not the people).

Growing up in New Mexico, the local news and state magazines always had "one of our states is missing" segments.
