Hi Franz,        I used a Poly-Fiber product called Superlite epoxy filler
(from Aircraft Spruce, I think- it's been a long time).  I found it very
good but there are many fillers you could use, I would not recommend bondo.
Any epoxy resin can be mixed with tiny foam spheres to make it sandable and
that will work.  The shperes are called micro-balloons, I have some if you
need them.  I prefer epoxy resin over poly-ester resin (that's what
boat-builders use), because the epoxy does not shrink.
Keep the filler to a minimum and remember that composites and aluminium
expand at different rates with temp. changes so it may crack along the
joint.  I chose to cut a thin kerf with a narrow fine saw along the joint
about 1mm deep.  If it cracked, it's inside this cut and I can't see it.
You might drop by Larry William's hanger to see what he used if you're in
Vernon.
