You know what I would do if i were you. If you use tapes to attach on the perimeter. I would simply just attach the tapes as is, and then use prothik spray to cover the perimeter of the unit. Then spray it with hair spray and come all of it through your hair. I do this for blending issues, hair color matching on the perimeter, and also to knock out the shine of the tape in certain areas. Then for the front you can use ur glue over tape technique.
