Right further progress:

Excuse the pic quality of the next few, I stupidly left a plastic film over the lens! A spit was bought to get much better access to the sills:



Upside down:



Drivers side to start with - this is towards the rear arch



'Small' blister by the rear beam mount



Sill





First sheet over the rear beam mount exposed





Area treated with Dinitrol RC800



Template made



Cut and laid in



Welded in



Flatted back



Primed for a bit of protection



More to follow

Thanks
