Yeah mate, thats true, although there is always the chance of an edge being missed if overlooked sparingly! Sixsixone, just an idea so that the problem can be prevented from occuring later on in the future, just check the condition and any signs of water leakage of your boot seal, tail light seals, rear windscreen seal and rear side air vent seals, just my 2 cents worth,
