Yep... some sort of horrible sticky black stuff under the surface of the sand... smelled very bad too...
This is what they looked like when they dried around 1hr after splashing around
This H2 was a rental and they put it back to the rental company like this...
This H3 is green...
Black H3 in front, Green one behind... 5hrs later they were "kinda" clean
Cheers
