BSZHTECH Leather Repair Tape Self-Adhesive Leather Repair Patch for Couch Furniture Sofas Car Seats Advanced PU Vinyl Leather Repair Kit (Dark Brown, 17X79 inch)

Thank you for all the information as well as your patience with my lack of knowledge. So it sounds to me that if I get a product such as this https://a.co/d/00CNHdwM then I will need one to go inside and under what is left (essentially installing it backwards), and then one outside to cover/hide the damage. Is that correct? And since these have adhesive built in should I get glue as well or just what is already on them?

i'd order a large vinyl patch, something like this https://a.co/d/0iaKWXA1
