As a short term fix I sprayed some automotive underbody sealant on the cracks, meant to prevent rust, etc. on the undersides of cars. Kind of an asphalt smelling, heavy black sealant. Not sure if that was a great idea but it seems to have sealed pretty well. Hopefully there won't be any unexpected chemical reactions...
Petroleum based products are a very bad idea on a rubber roof. That white product (dicor sealant) that is soft is the correct thing to use .
Like nobody said there are correct products to use. Petroleum based products will dissolve the rubber membrane requiring the replacement of the roof.
