How do you change a roof spoiler on a 306?

To change a roof spoiler on a Peugeot 306, first, remove any existing spoiler by unscrewing the bolts or clips securing it to the roof. Carefully detach it from the vehicle, ensuring not to damage the paint. Clean the surface where the new spoiler will be attached, then align the new spoiler and secure it with the appropriate screws or adhesive as needed. Finally, check that it is firmly in place and remove any excess adhesive if applicable.
