Here's his finished work, which shows the tiny gap (of just six inches) he had to work in to apply thick sticky bitumen paint to the wall. He ended up being covered in it - bugger, should've got a photo of that!

There are quite a few shots here, but it is a big milestone, so took a few!
Starting with the street view...
And here's some vision...
This is the end result - photos taken today.
