- DAP filler, the stuff used to patch walls does a real good job. It does
- shrink when filling deep holes/cracks so you should apply it in thin
- layers. It dries fast (15-20 minutes) and sands easily. When purchased
- at a home improvement or hardware chain store, this stuff is extremely
- cheap (much cheaper than the equivalent hobby marketed products) for the
- quantity obtained. I've used it on balsa and fibreglass, both of which were
- primed and painted over, and have seen no negative side-effects.

- You can also use epoxy and micro-ballons to get very good (and strong if
- necessary) fillets, contours, fairings, etc. The more micro-ballons you
- mix with the epoxy, the easier sanding will be, but at a sacrifice to
- strength; less micro-ballons, harder to sand, more strength.
