On the old house we're renovating at the moment, there is an asbestos
stench pipe, the one that connects to the lavvy and vents the fowle
gasses to the atmosphere and thus enhances global warming;!.

The pipe is in very good nick itself but is a rather sick shade of puce.
We want to paint it Black, but would the correct paint be Gloss Black or
perhaps something bitumen based like car body sealant?....

TIA
