Norice got some faint rust bubbles coming under the front passenger side front wheel arch, nothing major. On inspection looks like its bee caused by a tint bit of the inner wheel arch plastic coming away leaving a slight gap where water has got in. What are my options? Would this be covered under rust warranty etc??? I'm not that bothered as you can only see on very close inspection, but fully understand best nip this in the bud now to prevent it getting any worse.
