Where your looking at a corner I'd use what is referred to as cover tape. And I'd use that over those small cuts as week but make sure the patches have rounded edges . Epdm has a habit of peaking

You mean, cover tape like this?

yes exactly at least what i can tell from the photo. you'll need to see if that needs primer or if it is already applied and its peal n stick.

Ok, and I am betting I need "uncured" EPDM flashing tape so I can stretch it over the corners (red areas)?

EDIT: like demonstrated in this video
