(This post restrospectively added on 29th Aug.)
The vinyl covering the front windscreen pillars was in pretty bad condition so we took the opportunity to replace it.
The dashpad restoration guy sent me down some spare vinyl (the same as the stuff covering the new dashpad) for exactly this purpose.
Plus a couple of boxes of foldover clips from the local office supplies.
The old piece and a new piece of vinyl cut roughly to shape
I didn't actually use the heat gun while the clips were on but you get the idea. Heat gun on low and just enough heat to form the vinyl.
All glued and clipped up.
"Can I help? I won't steal any vinyl!". Yeah right.
