Really depends on what the material is. If Gore-Tex, send it back to Kokatat and they will repair it.
If it is made of Tropos, a coated fabric, once the seam tape comes up, new seam tape won't adhere to it again. Tropos carries a 2 year warranty against that issue.
If Tropos, then just use something like this to seal the seams:
Gedi Convertible Helmet
Recreational Kayak Paddle
PFD's (Life Jackets)
