Remove pine resin from the car
Who once stood in the south under pine trees, knows the problem. Pines but a resin that sticks horribly and is difficult to remove.
1st tip:
Ask for special pine resin removers locally, e.g. in Italy
2nd tip:
Treat stains with oiled cloth. That lasts, but finally works. The advantage is that edible oil does not dissolve the vehicle paint.
3rd tip:
Cover the vehicle with an old bed sheet or similar. This saves a lot of trouble and work.
