No, no photo's, although the initial result actually looked quite nice. Uniform thick black coating. Black like the darkest night in a cave black. Model T Ford black covering everything within the Cobb. Just like I'd taken it down the garage for a nice respray.
Coal tar soot however is, in the truest and most literal sense of the word, an utter flange goblin to get off. I'm on my third session with the Mr Muscle evil chemicals oven cleaner and a scourer and yet we are some way off seeing shiny Cobb again.
This is all my mothers fault. "Here's a bag of charcoal I found in the garage for you".
