Use auto paint with some plastic adhesive promter. You could go all out with primer and clear but gloss works just as well but dust will be your bigest enemy. Some let there models be free rollers meaning you can roll them. Short story I. Built a 1971 trans am white with the blue strip running down the middle me and my dad had it perfect. We painted the engine pontic blue and did up the interior with the proper blue it was a gem to behold untell my cat wamted on the shelf and destroyed it when it smashed all on the ground. Think thats why I love Pontiac's.
