2 - Wash frequently. Hand washing is so hard during winter, I usually take it to the local power wash and wash the crud off at least once per week.
Yeah, that's what I've been reading... wash every 10 days or so.

This is essential, or you will have rusted door sills in a matter of weeks. It is a simple fix to correct a TERRIBLE Nissan lower door sill design, but if you don't you will need to have the sills repainted. Check the glossary sticky post at the top to locate the thread, as it is buried.
Other than that, give it a coat of high quality wax and wash it when you can. The sheet metal is coated so undercarriage rust shouldn't be an issue like it used to be with cars from say, the early 80's.
I'm going to have to look into this door thing a bit more and contact the dealership. I took a look this morning. I don't see any noticible scratches, but there was a lot of dirt and water built up in the back door sills.
