Small Crack on bumber.
 

I have a small crack on the bumber where it attaches the the rest of the car. Is there is anything I can apply to it to prevent it from getting any bigger.

Take the bumper off and clean surface from the inside, then epoxy it from the inside.
That should prevent it from getting any larger or splitting.

^^ yea thats really all you can do... they make some good bumper/plastic repair kits out there... there is a company called SEM (they do autobody supplies) they make a 2part product called "problem plastic repair" and if you use that with some of their fiber roll that is really just a peice of a plastic like fabric that you squeeze onto the glue to add some strength it works great... i swear by it at work for bumper repairs... and its sandable to so you use it for the outer parts if you are doing finishing work.... what ever you get just make sure its plastic compatible...

Thx for the info guys...Ill have to do my homework on it later tonight.
