reflection edge artifacts on vehicle

I have been having issue with my edges on a hardsurface vehicle reflective material.
is there a work around with smoothing out the edge? parts of the edge are fine, others need some help


Have you tried to build your lighting with production quality?

It looks like SSR artifacts. You can try to increase its quality in post-process volume. Or something more advanced 3D Modeling & Texturing: [Unreal Engine 4] Improving Screen Space Reflections
