I would expect mine to fine as mine is about a week newer than yours!! I think it might just be muck to be honest as I havent had chance to wash it since it came back from the crash repair centre... I will give that rain-X stuff a go if I see it anywhere I am going to Cituning on Thursday to see if they can fuel my power hungry needs...they have a stage 1 tuning kit, here it is. That is very tempting, I will have to get it priced up
