I found that if I spread out my sprays I get more hits I guess from better diffusion but if I stack my sprays the effects seem to last longer.
I have mostly noticed this with Instant shine and Ammo but I’m sure it goes with others as well.
I think I read somewhere more sprays at lower mcgs will make for better diffusion.
I thought this was worth noting I found that if I stack my 3 sprays of IS it seems to last at least 7 hours but if I spread them out I get a good 5 and notice more people around me getting the effects.
