Anthracite headliner

I must say that I very much like the anthracite headliner in GBMINI#3; the dark color matches the other dark parts of the car and helps to highlight the red dash & seats; but the airbag warning stickers on the visors really stand out and look ugly on the anthracite – much more noticeable than with the light headliner!
So a bit of searching on MINI2 gave me a few threads (this, this and this) persuading me that I could easily remove the stickers with denatured alcohol, which we have at work.
I am pleased to say that initially, all went well and the driver side sticker came off quite easily …

 

Sadly at that point I got confident and impatient 😦
The result is that the passenger side visor is a bit battered from where the sticker came off in twenty million pieces and required a metal bristle brush to pick off the residue.
To make matters worse, I got a little alcohol on the painted dash trim – and it washed away the lovely red gloss finish 😦

Very bummed out. I can get a new trim piece ($70+) but Scott at MINI Peabody tells me the part is “on national back-order” … doesn’t MINI know how critical it is that I get GBMINI#3 looking pristine again *NOW*!?

So:
Remove the visor airbag warning stickers with GREAT care.
And keep the nasty chemicals away from all the shiny surfaces.

Why does the light stay on?

Normally this website offers answers – but here is a mystery and a question …
I have noticed that when I park GBMINI#3 and switch it off, the “P” light on the automatic transmission stays lit:

Even after the lights are off and I get out, shut the door and lock the car, the “P” light stays on.
Some “running-in-and-out-in-the-cold” experimentation reveals that the light stays on for between 3 and 5 minutes. I have no idea why.

Any ideas?
