Super Billy's cab - Repairing a slightly corroded cab

[Billy26F5]

Super Billy's cab has never been in great condition, but in the last 5 years took a turn for the worse. Fortunately it's now indoors, but it's taken ages to get onto it to start cleaning it. We're a very long way from any true repairs to begin but thought seeing the cleaning was worth it too:

Before any work





After the first session





and some other pics as a bonus








Note it's hot! This one is long after the gauge would have stopped registering in normal temperatures or in the barn.

Probably not going to do much on it for a bit as it's fairly tiring in this heat.
