Not that I should have to justify myself in a forum but I'm going to.
First I never post a question without first checking the search facility. Unfortunately not all questions are answered in the kind of detail I was looking for and often when someone posts a question they get solutions but never post which one solved their individual problem.
Second, I've just fitted an expensive speaker kit to my car and dynamatted the doors, therefore upon finding a leak it would be plain stupid to throw a bucket of water at my window and soaking everything to find a leak when I could ask a question here to find out if it's a trouble spot or common issue.
Third, if you don't like me or my question, ignore it and either post your own or move to one that sparks your interest.
Fourth, you shouldn't upset your customers, but more than that you shouldn't upset your friends, especially when on your birthday all of your others let you down.
Fifth, thanks fast guy for your answer.
