hi,
the texture on the heater panel and the radio bezel weren't in the plastic

it was paint

the best match youll have is a black wrinkle paint,
it does need to be heated for best wrinkle results, so be careful not to use too much heat or youll damage the plastic,

a hair drier or heat gun on low will do it,

although ive gotten best results from letting the item sit in the bright sun after the wrinkle paint has been applied
