Make sure uuse the silicon very, VERY !!!!!!, sparingly. It was used to fit the lower screen to the 1923 Peugeot Type 175 I owned and every hot day the silicon dripped out of the frame and onto the scuttle below it. Annoyed the **** out of me all the time. I told the bloke in Marseille who bought the car from me about the problem and hope he was able to fix it (maybe they don't get days over 25 so the problem might not arise).
