Cheers! I have one I found before it was done......although all we did was - give it a wash, wiped it down with meth spirits,then taped off the windows and rest of the body. I know a lot of people would completely sand it down first, but the paint I used you don't need to do that unless you really want to, if it fades in a few months time I'm not too fussed it can just be re sprayed..it's for out bush anyway! Here is the link I found though!
