Thanks guys. The bonnet has way more time it it than it should. Still needs some metalfinishing and tweaking. I should hav just made a new one - would have been quicker. There is now only 2 75mm strips of original tin on either side. Along with the lower part of each door (also modified) that's all the original VW metal left on the outer skin
Eben rust isn't a major issue. I try to wear gloves whenever I'm working - bare hands cause rust very quickly. I cover parts with etch primer if I am odne with them. Just sanded it it off now as I am nearly ready to start to paint now, and will be using a twin pack etch primer onto the bare metal.
One thing I did discover - rust converters and welding don't mix!!!
There were some areas that I put rust converter on that I couldn't access that well (heater pipes etc) Anyway I decided to add more reinforcing below the doors, and when welding it in the heat caused fumes that made all exposed metal in the area flash rust in minutes
-almost as if the rust had been trapped and now escaped and neede a place to go and sit
