Applying undercoat by spray turned out to be more trouble than it was worth and the finish was just as good from a roller.  So I applied another coat to both the o/s rear corner panel and the mudwing.   The mudwing will need a bit more flatting and another coat before its finished.   This week I have been making starter motor cables and shortening the dynamo cables so they will fit the control box when it is reinstalled.  I also applied filler to the bottom of the rearmost o/s panel where it meets the frame and is flat as it fitted poorly to the vertical beading just before the emergency door.
