Building my first 2m pattern ship which has a composite fuse and honeycomb formers, etc. I studied a lot of pics from PL Prod's web site and it appears from the pics that silicone adhesive was used almost exclusively for attaching the honeycomb items to the fuselage. The only exception is that in some pics it looks like epoxy might have been used on the firewall, but then in other pics it looks like silicone... maybe it wasn't the same plane in both pics... I don't know. I'm not 100% sure I'm looking at silicone in the pic, but the adhesive fillets look more like clear silicone than epoxy with micro-balloons to me.

My question is: Has anyone used silicone adhesive on honeycomb/composite fuse? Any tips or tricks with using silicone? Pros/Cons vs epoxy? Weight... is it lighter than Epoxy? Quieter?

Thanks, John.

Attached is a sample pic of what I was looking at.
