i paid around 4g for mine, custom colour, did the car including inside the doors and boot, didnt come out too bad, cant complain for what i paid, i tried like 20 places on the gold coast and they qouted me 4 g for standard colour not inlc inside doors and boot. so add that plus the custom paint and your looking at 6g more or less, just remeber, unless u have a mate in the business to look after u, u pay for wat u get
anyway, try fine finish bundal, they are great for what u pay
