The only problem with getting a SIMCA 1000 shell dipped is the way, as in many French cars, where thicker gauge metal is needed, they used two or 3 layers of thin stuff. That's where the rust problem arises in the first place with moisture getting between the original layers which were spot welded in a very hit & miss fashion from the factory. With dipping, I'd worry about the acid getting between these layers and staying there. Also, I'm building this one to a tight budget and when I originally built it the front end panelwork was bonded on as a complete unit which, dipping would have meant removing that. Aim is a fast road/trackday car eventually. The fibreglass rear doors I sourced from France for a previous racer back in the late 80s save a massive amount of weight with lexan windows. I've got the fibreglass front door skins from the same car ready to fit. Also I'm fitting a larger radiator in the front but it is an alloy one so should save a bit.
