I used folia-tec stuff you used to get in halfords. Heres a quick
guide to how I did the ones on the VR.
started off by getting some crystal clear rear lenses
then i set about tinting them
i left them over night to fully go off then added around 5 coats of lacquer, which when dry i sanded with sone fine grade wet and dry paper eg. 1500/2000 grit to level off the orange peel.
then just polish up untill they sanding marks have gone
