Secondary bond?
 

Have a glass fibre moulding, which needs to have another glass part bonded
to it, after the first part has fully cured.

Would I be right in thinking that an epoxy resin system, with proper filler
added so it aheres to vertical surfaces, would be the best way of going
about this?

TIA

Yes, but for best strength you need to rough up the cured part with 80 grit
sandpaper to also provide a mechanical bond.

I like to grind down until I see the threads of the cloth almost showing or
just starting to break through. Less resin better bond is a primary rule of
glasswork. It also fairs better.
I also like to thicken with milled glass fiber rather than the usual bulkers
and cabo.
It's the best way to strengthen the weakest part, "the resin".
