Talked to Dennis about it, and showed him the commercial.  He said that it is not an original car anyway.  Said that the grille is wrong, the hood is incorrect for the shaker, etc., etc.  He would know, as he has a 70 Challenger (I think it's a 70) back home in Illinois.
So it would not have hurt the value of the car in the least to get rubber on the quarters.
