flex-tend & barrier spray?

Hi there! So I've heard a million different opinions- is one supposed to use a barrier spray with the flex-tend extended wear wafers? By Hollister... I could just call Hollister & ask, but... I've tried it both way- doesn't seem to make much difference either way. My skin is pretty good, thankfully, so I'm really not sure if the barrier spray matters. My WOCN advised using it initially, to sort of "prep" the skin to not respond to the adhesive. But now I've become a fan of the flex-tend wafers, & I seem to remember reading somewhere that you're not supposed to use spray with those??? Any ideas?

Hollister specifically said not to use the barrier spray or wipes with their Flextend products.

I have used Hollister medical adghesive with several different type wafers, such as karaya, flexwear, and some kidn by coloplast- with no worries- haven't tried it with fkextend wafers though- just got my flextend pouches today to try them- hopefully I can use the medical adhesive as it gives a little more peace of mind inthat it creates a very sticky surface so that the pouch will adhere right away- been using it for 20 years (although you're apparently not supposed to use on skin- I've been doing so for many years- would rather have peace of mind about pouch sticking than to worry about cancer- too sick to really care about cancer at this point) The only real 'skin prep' I use is occasionally using liquid bandage spray when skin gets really raw- the raw skin makes thep ouch not want to stick even with medical adhesive, so I use liquid bandage, then medical adhesive over it, and some on barrier itself, and it works pretty good- I just don't trust pouches without any kind of medical adhesive- and too chicken to even try-
