Yes, brilliant, -like most REAL experts he makes it look SO easy and is so quick.
After lunch Muskrat?
I used to work with a finished artist who did work even more demanding than that tank lining. Terry. He was a dead-set alcoholic, awful shaky hands and all. His best work was AFTER lunch of at least 5 or 6 heavies, he'd then sit back at his desk and instantly his hand would transform from fearsome shake to dead steady as he freehanded the finest line-artwork.
Dear ol' Terry. Heart of gold, and a great drunk.
