Thankyou Jim I just used normal car paints I stripped it all out and sprayed it all individually using plastic primer as a first coat then normal primer as a second coat then I done 3 coats (to add strength) of exterior car paint on top of that and left it for a few weeks to make sure it set quite hard before putting it back in, the colours is BMW imola red ii and Toyota white 040. Was over 2 years ago that I did that now but still in good condition really, I had done the same to the interior of a golf and a corolla 1st as practise and to see how it would last and seems to last really well. On closer inspection you can see where I have masked certain parts but I do get quite a few compliments on how tidy it has come out which is nice
