Google automotive interior paint or dye. There is specific stuff that for paining interior plastics. You can get stuff that matches the OE colors pretty close, or go custom. Make sure you put time into prep work and get off all the armorall first. then do the adhesion promoter and paint. I would only do clear coat if you do a bright color.
dont use regular spray paint, it wont bond to the plastic and will chip again, plus it isnt flexible.
