How to add any picture on a Car body in Photoshop

Here I could not add Voice Instruction. SO I am Explaining those steps here:

1. choose a the car image and the picture which you want to add on the car.

2. select the area where you want to add. You can use pen tool or any lasso tool ( it depends on your comfort). But I use pen tool for selection. 

3. Then create a new layer and fill it with white color.

4. and select the car layer and and do Layer via copy ( Short cut key is CTRL+J )

5. Copy layer will be on the top and hide it for now.

6.keep your design image layer on the top of  white fill layer

7.right click on the design image layer and do clipping mask.

8. change the layer mode normal to multiply of white fill layer.

9. on the the top layer where you copy the selected area of the car.

10. disaturate the copy layer ( short cut key SHIFT + CTRL + U)

11. Change the layer mode normal to screen. and make a nice contrast between white and black  with use of LEVEL OR CURVE adjustment

this is the process of add picture on a car body. Here I am not explaining the making of reflection which you can see at the last of this video.
