Achieving an effect where paint is layered at the Edge of a Surface

First of all, Thank you ^^
You mean, I should “Just” Model it out… Youre kidding hahahha.
Thats a good idea (To be honest I didnt thought about this completely logical approach hahaha)

With this Mesh it would be possible without any doubt.
I was thinking about “more Dirty CAD Meshes”.

What I also thought about was, to make a flatten mapping (bake an edge Channel out of Substance) and put it into the second UV Layout to combine a Normal map based on the Bake and the Triplanar Mapping of the Automotive Materials…
