My wife and I purchased her a red 09 xterra about 3 weeks ago and so far we love. This is our first X but not our first nissan. My question is what is the best thing to use for keeping the top plastic in good shape? Do you wipe it down with armor all or what? We looked at some used x's that had the top and front plastics faded out and it looked terrible so I wanted to keep it protected with some form of uv protector to keep it from happening.
