Which one do you apply first?? I thought this was a great question proposed in Fitness Magazine (July/August 09). I am sure they won't mind that I borrowed their answer!
According to experts the answer is sunscreen! Because sunscreen sets a film on the skin, you want the bug spray to be on top. Make sure the sunscreen is completely dry before you top it off with the bug spray.
Choosing a repellent that does not contain ethanol alcohol will ensure that the sunscreen does not break down.

I have not tried it yet, but plan to!
If you try it...please comment back. I would love to hear from you!
