Because you are in the East, wash the bottom of your car regularly in the winter. Drive carefully to avoid accidents. Even it is others' fault sometime, it is your car that will be damaged. If it is sunny, try to park your car in a shadow. That 's it. A car is made to be used. After three months, you will not pay so much attention to your car. I know a lots of people who buy a box of wax for his car but most of them can not finish the wax. Sometime the same is LP;-)
