I'm trying to model a car, when joining two hood and the fender I had to tweak to geometry to make everything quads but I ended up with sort of bump as you can see:

enter image description here

Here is my topology:

each time I try to move a vertex to remove the bump I create another,

Is there a way or an add on to get perfect curvature?

Here is the file:

Maybe you should use a simpler topology. I've done this from scratch, using your object underneath, first I've used the Snap option then the Shrinkwrap modifier so that it sticks to your object. Maybe you should use the same method, but starting with a duplication of your own mesh so that you have the right amount of edges...

In blender 2.8 you can try to fix it with the smooth laplacian in the special option (w -> smooth laplacian). It tend to keep the general shape while smoothing "wiggly" surfaces.

For more info see the official blender documentation: https://docs.blender.org/manual/en/latest/modeling/modifiers/deform/laplacian_smooth.html
