I would say none, It all depends on "Coverage" and by that I mean with some colors it takes two coats for coverage and others it takes 7 or more coats for coverage. Thats just with the paint, if your are just going to respray it will be added weight. If you want any weight savings through body work you will have to strip the car down to the metal and 'properly' repair any damage ( ie. minimal, if no body filler) and change any original panels to aftermarket or reproduction replacement panels, and very minimal amounts of primer. If you were asking about modern base coat/ clear coat systems I would not use any "high solids" clear coats as with our Sikkens brand paints I have seen a noticeable increase in the weight of the cans that get delivered. This is all paraphrased but to sum up I dont think you will see any reduction for the costs that will be involved.
