I'm thinking about painting the main trim piece that goes around the gauges and down to the hvac controls. I was going to match the color of the car and add a little something to the interior to offset the dull dark gray. Now this piece is smooth, but slightly textured. Is lightly sanding it recommended before applying primer? And what primer/paint is better to use for the plastic trim? I don't often do anything to my cars other than general maintenance, so I apologize if this is too easy lol. Thanks for the input
