No need to go overboard there. Run a little 120 grit paper down the cut, put a piece of guerilla tape around the edge then glue the TPO down. Works great, and yes, I have done it myself so I know it works. My RV tech buddy, who literally grew up in the business gave me the tip.
The fly in the ointment here is that I am using .060 thickness which is reinforced and does not bend well around corners.
I can check, but I may still need to round off the corners. When I did the sides, I rounded off the top edge, and it seemed to help it make the bend.
