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.

I am stripping my bottom paint this fall - actually I am having a highly

barrier coat that he sprays on over the DIY "roll-on" systems from
Interlux,
Petitt, etc... since I really don't know the difference I would
appreciate
anyone commenting on it. Thanks. -DanO


I don't know what a "coal-tar" barrier coat, but it doesn't sound like
anything Interlux would adhere to....

I'm not sure I would characterize the "roll-on" systems as DIY... if
that in any way implies that they are less than professional
chemicals.
