Check regarding the tar. I think it is most likely coal tar epoxy .

so this?
that has to be the cheapest marine coating i have ever seen...

I painted the inside with the same thing that went on the outside. The surface prep is key to it lasting.

does it rub the black onto your hand when dry?

Looks like it's about half the cost of Interprotect.

how would you get it off?

Wow… that brought back nasty memories of needle gunning old coffer dams and applying what is basically economical bitumastic paint.

The Bitumastic Range of Coatings from Paco Systems

I am quite convinced that the real attraction to some ship owners using this stuff is that its thick coating hid a lot of sins away from the Surveyor

If old steel...light sandblasting will get it off

I have never seen coal tar used on pleasure boats but, it was a common coating on steel commercial boats, like tugs and boom boats. It went on thick and covered a lot of sins. Coal tar epoxy is newer like in the last 40 years or so. Coal tar was relatively inexpensive but the coal tar epoxy was much more expensive.

I've seen 1 aluminium hull boat with coal tar on the bottom.

Hmm... not sure if I am right here but AFAIK, coal tar epoxy has been discontinued - at least for non-commercial applications - too many HSE concerns.
