Considering I got my TL piece and need to make the arrangements to learn how to do this stuff myself completely, is there any way i can send my piece back in to lower the density a little bit or even the possibility of a graduated hairline?

DiDi wasn't too sure toplace's standards when I placed my order and I wasn't too familiar on densities as well, I beleive my piece is like a 70-75 but I believe lower will blend well.

Also I'm interested in this knot sealer idea.
