My door seals are trashed and the door sill rubber strip pad has shrunk by nearly and inch so it is time to replace them both. I don't like the idea of using the doubled sided tape on the door sill rubber (due to trapping water underneath, etc.) so I removed all the old glue and will use the 3M adhesive to install the new door seals and door sill rubber.

I noticed that the vinyl covering, shown in the picture has lifted. If I stretch the vinyl flat, I can make it wrap around the edge. Any recommendations as to what to use to "re-glue" the vinyl and how best to do it? Do I use clothes pins to clamp it while it dries?
