Filler is not always such a bad thing with epoxy. When gluing wood, people often add filler to add flexibility or to fill gaps. Otherwise, epoxy can be too stiff and crack. From what I have read, epoxy often appears to crack internally near the epoxy-wood interface: you then have the curious situation where the joint remains good but the adhesive fails. Wood and epoxy is a topic of current research.
I used a 90-min epoxy on my passenger door panel but next time will probably use a more flexible, two-part polyurethane dispensed through a static mixer.
