Cleaning and waxing:
After I bought the car I cleaned and wax it to have some protection during the winter. I couldn't find any rust problems, just a few paint scratches where it was tiny surface rust, easy to fix when the summer comes, until then it's protected by the wax coating.
I didn't do this very special, just wash the car very carefully and then put the wax on it. It wasn't very bad before either.
Along the car goes lines over the hood and roof, also the interior. For me it looks very nice and give a special look.
And the look of the back? Some people love it and others do not. For me it's ok.
