No idea, BB. I have heard of people complaining about sweat and sunscreen, but have never investigated the issue. Check out the comments on my post... some of my readers are proving some interesting analysis.
I'll be writing a post about running shirtless in the near future, based on the idea of thermoregulation and increasing vitamin D production as a means of preventing internal cancers.

This is really interesting, Jason (I'm sorry I spent a fortune on those fancy shirts...). I run here in Australia (Gold Coast) where it can get really hot and humid. Would sunscreen effect one's ability to sweat and regulate properly? I can't imagine that anything over 45 minutes under our sun without a shirt and sunscreen would be good. Or perhaps just stick with the cotton shirt?
