Ahh Fordwich.
My sons played hockey in that area a few years ago during travel hockey times...good memories. That's just outside Wingham/Wroxeter if I recall correctly...about an hour or so away. It's a small world for sure.
And yes, patience and a little extra work will certainly help smooth the wrinkles.
That steam/heat gun method shown in that video really shows how the leather snugs up.
My Audi seats are showing a bit of stretch in the seat bottoms from my fat arse...will give that a try when spring has sprung to tighten them up.
Keep us posted!
