Generally that applies more to the none products like ammo.You should probably start with only 1 spray for ammo.I find that unless its buffered with the socials,i can only get away with 1 spray around my girlfriend(>_<)You should follow the guide to sweet spot testing though and find the dosage that works for you since everybody is different.Can check out the link below to find out how.
