Filler Mixology

I posted a thread previously titled "Sanding block wisdom," to help filter through all the collective knowledge and opinions regarding sanding blocks. The responses were really helpful and I appreciated all the information.

This one is about body filler. I've seen many comments, as part of other threads, about what I'll call "Filler mixology,"
Many seem to mix their favorite filler with a variety of other fillers or additives (I.e. Evercoat plastic honey.)

I'm sure this is a matter of personal opinion and experience, but here is the question:

If you are using a good quality filler (I purchased Evercoat 125 Rage Ultra) and are using the correct hardener in the correct ratio, what is the benefit of mixing it with other fillers or additives? Or, does it work just fine on it's own?
**I'm aware there are unique situations that call for special fillers, I'm just interested in basic filling of low areas and minor dings in major body panels.

Eager to learn!
 
From what I've seen on internet videos, plastik honey is used when skim coating large flat panels such as a hood or roof. It can really thin out filler to flow, almost soupy if you add to much.
 
In 2021 the only thing you need to concern yourself with regarding mixing, is whether you want to add an extender type product to your filler or glaze in order to extend the working time of the filler. Useful when skimming large areas or multiple areas in temps above 85 degrees.
Example, Evercoat makes the Rage Ultra Xtra specifically for that purpose. You can extend the working time of Rage fillers and certain Evercoat glazes with it.
Everything else is unneccesary, especially with the modern fillers that are available now. K.I.S.S. as my Dad used to say, :)
