Scuff and dirt Jay!
It'll be fine - there's an 80A master fuse on the battery, so that will blow before it catches fire (fingers crossed).
Deano - the DIY feel is what makes me feel at home!

http://www.theplasticman.co.uk/index.php?area=calculatorAcrylic (Perspex) sheet - 5mm thickness available in "Ivory".
Specify one hole and put dimensions in the narrative.
For the Roadster it was 360mm with a 160mm hole, but double check. Get it right and it fits perfectly, holding in place with two small neoprene pads. It arrives with protective film on both sides, so you can chose to keep one side protected, although I strip both sides. A fantastic piece of plastic. Laser cut, with polished edges, and as clean as a whistle.
