Yes bro, the Antirust will be Applied on All panels inside, Once the Door work is done then will move inner side of the car and will scrap all rusted area and then will Apply Antirust Damar Coating everywhere.. the last part will be , Engine will be taken out and then will scrap t he orignal paint and then will put new paint there..
the Car will last more 15 to 20 years after this treatment because this Car have only 20% rust since 1986 and that i was amazed to see..
