Just done mine in the last week or so - painted it in homebase emulsion - silver mist, dregs of what was left from painting the hall.
Looks silvery/grey white in landy, looks like very light blue/slivery in hallway - go figure!!
I used the head of a broom to clean off the evil orange foam/stickiness - one with green plastic bristles, pretty stiff but with just the right amount of 'give' if you get me!!
Took a few hours on a bright, sunny with a slight breezy day. Did it on me lonesome including stripping the interior and getting it out of the disco. I put it back in slightly damp as I figured it would be a bit more pliable - now I have the odd dusty/grubby finger/hand print on my headlining - but it shows it were done by me own cackhanded paws!!
I may even change the colour and go for a more grey colour - depends what I find on me next DIY store outing fer a few quid!
