Crack in driver door armrest 06 LaCrosse
 

I know from the picture it's hard to tell but the crack is about 3 inches long. There is a dimple in the foam under the crack. I guess from my big bony elbow! https://cimg3.ibsrv.net/gimg/www.bui...c20928790c.jpg
Anyway I wondered if anyone has run it to fixing something like this? I would like to fix the dimple in the foam before I try to fix the crack if possible.
