It is a black tar like product. It can do a adequate job as a barrier
coat, but it is a bitch to prep the surface when it is time to repaint the
bottom. The tar clogs the sandpaper and it takes 10 times as long as it
should to prep the bottom.

I would not recommend anyone use it, when the epoxy barrier paints are so
easy to apply.

Thanks. That's pretty much what I was thinking. -DanO
