We used to have a blacktop drive, sealed it with the filler version of the coatings and it worked out fine. I filled a crack with sand and tar before I did the surface.
Guy across the street paid to have his done and in 6 months it was worse than before. He thought the guys used diesel or used
oil. He was pi$$ed.
I think it is in what you use to apply the coating.
So why are you asking???
