Coloring the footboard doesn't reduces the value of the car neither it is considered as accident, therefore you can go for proper denting and painting of footboard. As far as the door is concern, it is better to go for dry denting in that case color remains. In case you want to claim thru insurance and for that you need to have the dent on the door, then ask the painter to paint only the dented area instead of painting entire door. And the last option is leave the dent as it is if color doesn't peeled off. IN case the color is already peeled off then you have to color it either qalam of proper paint to avoid rusting. I hope above detail reply serve the purpose. Regards
