I apply Davlyn to the skin perimeter only , about inch wide or so , like today .
To the unit base only !
Let it almost completly... to completly dry. still a little tacky to the touch.
This initally application is adhesive to about 9/10 days.
Seems to keep on staying sticky , especially when base is wiped off with alcohol in conjuction with a base rinse off.
Spray with G2bG Spiking spray, head and base. Also at times, I , lightly coat both surfaces with their ( G2bG ) Rubber Cement . Followed by kinda lightly pressing and pulling away,with my hand both surfaces. Helps to kinda make it tacky !
Apply unit , pressing all over.
Xeon....this is good for as long as you want, 10 days , couple weeks (the unit ) ...your call.
Of course daily rinse offs and at times alcohol wipes of the base. Acohol not only cleans but seems to revive the adhesives still on the base. Do as you like with your scalp under the shower...., just rinse , or shampoo. I don't shampoo everyday. But I do soap lather up !
Now as I told Oldwearer ...from that first day on , only when the Davlyn is applied...the subsequent attachments , when I reapply the G2bG products , whatever I choose to use that day, ....spiking spray , or combined with the rubber cement , takes me a couple minutes at the most !! Try that with lace ! I don't think so ! ?? Altho , I could be wrong !!
Also during that 10 day or so period , I may use a strip of tape , applied to my head only , and/or maybe a refresher dab of Davlyn , here and there , or over the complete perimeter, takes like 10 seconds to do !
Thats my procedure and works well for me , over the last 20 plus years....Hope it works for you also ! But like , Xeon, everyone is different ! But don't know if I buy into that completly ! ?

Take care...thanks,
