Well in keeping this in the spirit of friendly information sharing we
have started....isn't talc a very heavy alternative? Are microbaloons
not a bad idea for structural fillets?

It's worth what you pay for it.

Great way to waste good epoxy.

As the old saying goes, "Buy em books, they eat the covers."

OK for talc, but for microballoons you are getting screwed.

Talc does nothing but add dead weight.

As far as micro-balloons for structural fillets are concerned, depends on
what you define as a "fillet".

If it is simply a fairing putty used as a gap filling glue with a fillet
formed by a popsicle stick, that is one thing, if you are trying to bridge
say a 1" wide fillet, that is quite another.

For small fillets, NBD, for large fillets, cover putty fillet with a piece
of glass and wet out with epoxy.

As an example, the bulkheads in my boat were installed with a fairing putty
fillet covered by a piece of 24 oz DB glass, about 8" wide to bond them to
the hull.
