I know what it's like to not have tape stick. If it is any help, I have NEVER been able to get tape to stick to my lace when applying the tape to the lace first. What I did was apply the tape to my head FIRST, then after spritzing the tape with 99% alcohol, I attach. This worked for me. For the hairline I draw the contour placement with a pencil, and apply the tape according to the line. For the sides and back I attached on the bare scalp as close to my hair as possible. I no longer tape the sides and back anymore since becoming a "convert" to g2bg, but I still tape my hairline by this method. And my current unit isn't a TP unit. I was able to get a 4-6 week bond with this method. I still don't know how ANYONE can get tape to stick to lace first. Anyway, you have another option to try if you wish.
