Years ago someone at Statueforum recommended me,
Zap-A-Gap Medium CA+ (the green sticker). I buy size PT-02, bcs my guess is the volume of glue will not harden/dry-up to quickly in the bottle after opening.
It is very good and strong, even larger areas and you only need very little. Bit pricey, but I can use this bottle at least 2years. I am using my fourth bottle atm.
When I look at the Bob Smith InstaCure+ BSI-133H you mention. It says works best with; Balsa and soft wood ?! and works good on many other materials.
Also price of ZAP is the same as the BobSmith.
Zap-A-Gap; Bonds virtually anything and has small gap filling ability.
