Prep Luggage for painting

[timgray]

I am repainting my 83 this winter. In the process of prepping, I'm stripping everything off the painted parts for a color change. I drilled out the rivets to seperate the trunk and saddlebags into halves and got everything off them except for the aluminum sealing trim. I really want this off for the painting so that the final job looks it's best. I removed all screws and drilled out every rivet yet I still cant get this stuff to release fro mthe plastic trunk and saddlebag halves.

 

any tricks to removing this without breaking the trunk or scraping up the aluminum trim/seal track?
