A lot of people who use skin also like the freeze spray.. But yes I would say that spiking glue and the freeze spray are the most common ones.

Johnny has a skin system,, I don't recommend applying either to Lace directly. But on skin you can if you want. If your attach skin with spiking glue, make sure it dries enough.. the trick to minizmize lifting is to make sure all of it is stick first before u apply. With lace.. theres air ventilation so it can dry on its own through the lace, but with skin it might be harder to dry if you put it on too quickly.

I got a solid base attachment but both products suck for me at the front hairline.
