unfortunatly it had side windows in it [but it was free]............... so i looked at buying window tinting film for the windows...... but it expensive and a nightmare to get the bubbles out.
second plan was to get a vinyl company to cut some sheets for me........ 2mm of vinyl... 2mm gap....2mm vinyl etc etc....
so basicly you have loads of stripes on a sheet.
cut them to size and apply........... quite easy because air cant get trapped.
the result is a window which is slightly coloured...ish, and inside visability is great.
i had silver........... but on reflection orange would have been better
