If you have time, then get some Weldwood Contact cement and coat the panel and the foam. Place the foam and trim to the edges of the panel leaving a small amount to allow the leather to pull in tight to the metal panel. When you put the leather on, use the contact cement and stick it to the foam, then stick it to the metal panel after the surface glued to the foam is dry to be sure that you get a good tight stretch of the cover material.
