I’ve pretty much finished this repair panel now, I’ll probably spend a bit longer on it to get the front to fit slightly better:

While the paint on the inside of the repair dries I decided to give the front pedal belly pan a bit of attention. 

Before:

After an overnight soak in a bath of Deox-C (it didn’t quite fit in the plastic box I had, but this shows how good the stuff is!). This should be useable once I’ve finished cleaning it up, patched a few pinholes and given it a coat of paint.
