Reading another thread made me think about the problems I have been having with ptexing my skis. I might be doing something wrong.
That is the core shot.
Anyways, I have re-ptexed about 6 times now. every day I ride, the ptex cracks and falls out.
in ptexing, i cut away the edges of base, sanded everything down, cleaned with rubbing alcohol, then drippped ptex in. I then waited for it to dry and sanded it down to a nice smooth finish.
