The Danish climate is tough on older cars, especially those designed for drier climates. One solution is complete after-market galvanisation. Look at this Citroen 2CV to see how it appears when so treated….
There are two 2CV specialists in Jutland, one is the Danish 2CV Centre and the other is the 2CV Expert. One of these two offers a complete galvanising option on refurbished 2CVs. The Danish 2CV Centre has a museum which I have not visited. I had a look at this car which seems to have undergone the maximum degree of protection but has not been painted. The robust style is consistent with the 2CV´s character and one wonders why Citroen didn’t think of offering this option for Scandinavia where the weather is bad and the road-speeds low. The car still had signs of rust on it here and there. That says more about the climate in Denmark than the value of galvanisation, I would say.
