I have a 79' 240D and have been doing the maintenance on the sun roof as per the Mercedessource kit. I have found that the air dam has a bit of rust on it and I wanted to remove it and clean/treat it with the anti-rust paint but I am unsure as to the best way to remove this. I am afraid of breaking it if I force it. Does anyone have any sequence of steps used to properly remove the air dam??? Thanks.
