In The Netherlands, all the Emergency Services have stripes, called “striping” at their car. They are blue and white and guide the traffic in case of an emergency. Please use this google image page as examples. All the ORANGE cars are Lifeguard-cars.
For my own lifeguard-cars, I also want to add the “striping” to the models. Although there is a huge “deviotion” between a flat surface and an curved door, I have no clue to do this.
Don’t think about adding stripes as if you were applying tape to the surface of the real vehicle. Divide the surfaces of the door and the fender so you can paint the areas different colors. I set up an array of rectangles that are tilted at 45°. I made a component of the rectangles before moving the whole thing into place. That makes it easier to remove the rectangls when they’ve served their purpose.
You could also look at using the native Drape tool, or the rather special Super Drape by Tig. If I remember correctly both of these would require you to position your model so the stripes can be dropped on the faces you want.
