Go to a marine supply/boating store and buy a tube of 3m 5200 quick dry. This stuff is incredible and will allow the spoiler to flex without breaking again. It is sandable and paintable. Warning ! Do not put this stuff anywhere you don't want permanantly bonded together. The only way to break a 5200 bond is to cut it ! Is there anything tricky I need to know, or do I just get under there and start un-bolting it? Tomorrow is the day I'm finally going to do something about that crack that's driving me crazy! Thanks!
