Layered material issue - white edge at the place two materials meet

[Perishock]

I’m trying to make a layered material that blends metal and rubber but there is a white line between them i can’t get rid off. I managed to make it thinner but still, when the camera moves away from the model, terrible artifacts show up.

Looks very similar to my current issue… Any chance you’ve found a fix?

CheapContrast with Clamp worked well enough for me but I guess this is not a perfect solution
