I've dyed several plastic parts....dash pieces, door panels, 08 consoles.
If you decide to "paint", I'd suggest finding someone to color match and mix up some dye.( Orileys has 2 stores within 25 miles of me that mixes paint. ) Also suggest you have them put it in an aresol can.
after getting your dye mixed/ parts removed
Wash parts with dawn dish detergent...it breaks down greese/oil
( I use a scotch bright pad instead of a rag...scotch bright pad also "scuffs" the surface of the part.)
Rinse washed parts and let dry
I use a rag with rubbing alchol(?) to wipe down the dry part
Get a can of SEM adhision promoter, and follow the directions...light coat, wet coat...
Spray the parts with the dye, light coats until the parts are covered. I spray the back of the parts too, around the edges and anywhere that may be seen.
Its more time consuming than anything.
