your wife a smoker? then coughs..
I have old vehicles .. I polish my head light lenses with plastex polish..
I then had scratches on my center console on my 1996 Impala.. not deep but it also looked dull since it is over 20yrs .. I removed it and polished it up and it looked like new no damage perfect ..
product is for plastic will not do damage ..
I do not know how to remove this on the runner .. only 10 bucks on the plastex ..if it works then lookup how to remove those parts.
