Hi Mate...Is that black tar shyte covering an obscenity?...If they are in reasonable condition internally then it might be worth plastic coating them..Ziga

Looks like some sort of hardened tape / matting. Rock hard but no idea what it is. Clearly covering something, perhaps that seam had split?

As for inside, can't see, this is my best shot

Hmmm... Yeah, I reckon that tape is a "Bodgit and Hope" repair job.... (unfortunately)
