Based I think on a Fistful of Lead game video that Jaye and his son played. I’ve done it a couple times solo myself.
Nope - original thinking I'm afraid, based on the fact that I'd bought a water waggon 2 days earlier and finished painting it in the morning, as the Mad Lord was arriving in the afternoon.
I was pleased with my dry brushing and wanted to include it in the game which is why it features prominently in pics3 and 7.
See my blog post for the details.
Cheers
