Looking on the bright side it may keep values of the galvanised chassis cars high?
The cars have come on a long way since steel bodies and painted chassis in the 60s and 70s - I once saw a late 70 s car that was one owner and had very low mileage needing extensive restoration.
It put me off buying a non galvanised chassis car and one of the reasons I bought mine new off the dealer.
This new coating is likely to be better than the previous paint and hopefully will not peel off like the stove enamelling on the caterham I used to own.
