Yep. Fresnel is fine for clear glass, diamond, water, etc.
For colored glass, or cloudy glass, or blue water, or a thousand other things, you have to separate the refraction from the reflection.
For anything that is opaque, such as car paint, it's not at all suitable.
And then the Fresnel effect becomes your responsibility.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
