You briefly mentioned those swirly-glinty-highlight-scratches on car paint in the beginning of this video. I have tried that as well, but I find it very tricky, because don't want to have those scratches really visible away from the highlights
Have you read this old blog post by viscorbel (orignal was taken down): https://m.blog.naver.com/PostView.naver?isHttpsRedirect=true&blogId=sakdon&logNo=220030534072
That method is probably impossible to recreate with F-Storm (as with Blender) because there is no stacking materials, as you mentioned.
Some have managed to do this effect with anisotropy, which seems to be a better solution to me, as it only affects the highlighted parts: https://www.artstation.com/artwork/nYOveX
This method goes back to Grant Warwick, he showed it in one of his old shading courses. You probably have seen him do it before. The problem with this approach is that it is very finicky to author, as there is no real control over anisotropy apart from the strength and 0-360 rotation.
Anyway, I would love to hear your thoughts on how to achieve this effect.

Just went through this one and the car paint one. The chrome came out really nice. The car paint was a bit tougher to get right (using Blender cycles not F-Storm, but after two hours of tinkering I'm satisfied with it as well.
