Ok, I know you all have some things to add here.

Here is what I screwed myself on...

The past 4 months I've had these freakin horrible ripples along my hl, so I've been doing the comb down to cover, I could not figure out what was going wrong all the time, was I pulling to tight, not enough, was the piece made wrong from my template.

None of the above on my all SFS and Supertape attachment all around.

It was the darn hair dryer!!!!!!!!

I was putting my hd on high heat and heating it up before applying so It would get super sticky.

Last application no hd and absolutely no ripples.

In summation, don't heat your head(this maybe ok to dry but i wouldn't heat it up) and absolutely don't put heat on the piece after the tape is applied.

How about some adds from the vets here.
