Dunno about this one guy,I heard that it's teh ghey for dudes to go tanning so yeah,it'd be bad in that respect.
Seriously,I'm not all that sure I do know that Napalm's carrier allows for fairly quick absorption but to be on the safe side I'd wait an hour after an application to begin tanning.You may be able to get away with half an hour though,I'll get someone else at Avant to verify the time frame .
