ok, I just got off the phone with Thompsons, I was told that in my region due to EPA regs they are not allow to ship solvent based product. So, they now make the water seal with a water base. It was always safe to use as the solvent evaporated over a few days when it was solvent based and they say that now since it is water based it is even more safe to use. Although, the area to be treated MUST be completely moisture free.
As soon I started the conversation I was stopped in my tracks, the woman said that everyone has been calling about the milky white product!
