I have a 99 Civic Si with a Razzi ground effects installed. The kit was installed on the car before I bought it so I have no knowledge of how it was done other than what I can see and assume.
Fram what I can see, the front dam is dropping (its dropped about an inch to an inch and a half). I can also see the velcro and caulk that was used to to hold it. The velcro is out of place and is doing no good and the caulk is no longer holding in places. The kit is mas of ABS Plastic.

Is there a way to safely remove the dam? Do I just pull it off and hope for the best?

Or alternatively if removing the dam is a horrible idea that could end up breaking it, what is a good bonding adhesive for ABS plastic and whatever the bumper is made out of?

Sorry if this is a bit vague.
If you have any questions, Ill try to explain it some more because Id really like to fix this...it looks bad.
