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.

I would consider Interlux and Petitt epoxy barrier coats to be DIY projects
and the product to be rolled on by paint roller.-Dan
