Ideally I'd of put the metal van panels in but you can only get them from Vauxhall and it looked chavvy turning up at jobs in it so just for ease I had the windows vinyld and tinted the rear window so you couldn't see through.
I don't know how good of a finish you'd get cutting some 1mm metal I think the curve of the window would be too hard to get looking good?? If it can be done I'd do it to mine and have it sprayed as it does bug me the colour is off when I look at it side on. If you manage to sort this out let me know I'll look into it for mine
