Question: "The passenger side of my car's floor is wet after it rains. I have a convertible roof and think it's coming down the window pillar. Is this anything to worry about?"
Answer: This is quite common on cabriolet hoods and nothing to worry about unless you have a Porsche, then you should panic.
Usually the fittings of the hood need a good clean out and the rubbers gently massaged with a special product we have that softens the rubber back up and helps it go back into its original shape. Usually this fixes matters and if not, it's possible to order a set or replacement rubbers which doesn't cost the earth... except on Porsches. They can be relatively quite expensive on some cars, but some cars are relatively quite expensive, so nothing to worry about.
