We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Bovvered? saying something like:

I had a new windscreen fitted yesterday, it wasn't until I checked
later that I found the fitter had left grubby finger marks all the way
up and down the 'A' pillars. They are covered in the same stuff as
the headlining, a sort of cheap thin stretchy material. I've not had
much luck in the past with cleaning this type of material so just
wondered if anyone had any recommendations based on personal
experience.

I was so exasperated with the grubby plastic headlining of a van cab, I
just emulsioned it black. It worked, too.
