So next Friday I’m going to a concert and I was wondering what should I use. I was thinking to use instant gentlemen or Summer ammo but I’m not too sure. I’m still testing these out trying to find out how many sprays I need. I anyone has any suggestions please leave here thank you. P.S. I’m 16 My arsenal: Summer Ammo , Shine, Instant Gentlemen, A314b, P97 .
The only one I would go with if I were you would be summer Ammo and maybe Instant Shine.
What sort of convert is it? Also, indoors/outdoors?
IME, more simple/direct mixes tend to do best in concert/large event situations - you generally don’t have the opportunity to more than basic getting to know you stuff, so complex and nuanced personality-targeting mixes don’t get much of a look-in. 
So to that end, Summer Ammo on its own or with IG would be my choice for primary on a young guy - You could add some Shine as well but temember there is some TAA in Summer Ammo already, so probably only a steering dose will suffice.
