Boundary Layer

I have a 3D body in a rectangular domain. This body is a body of a racing car and one of the questions I ask myself is, is it necessary to apply a boundary layer to the body? If yes, should I apply the boundary layer on all body surfaces?

I was looking at one tutorial where they import the IGES file of the car body and in that tutorial, I am surprised to find out that they didnt apply the boundary layer. So can anyone advise me if it is necessary to apply the boundary layer? Thanks

Look here

It depends on you y+, so if they don't create a boundary layer in the tutorial the y+ is probably above 30.
