Post a pic of your cat here

You certainly know your stuff mate, and not the first time I've been in awe of your photography. If it's not too cheeky an ask, I'd love an electronic copy of the final result you've posted here so I can have it blown up on a canvas.
 
Because you're in total darkness the camera won't pick you up....the exposure was about a minute with me walking all round the car.
When finished light painting switch off torch..open door and flick them on quickly
As above.....make sure interior light is off or you'll illuminate the interior when you open the door
