Contact them and ask for epoxy in tubes for glueing. Rapid for 5/10 minute cure and a couple of tubes of slower/stronger 12 or 24 hour cure. Hobby shops and DIY hardware stores should stock them. The supplier you have listed is for large scale boat building in resin and glass fibre construction, a different kettle of fish, but they should sell the glues too. Just tell them what you want but they may only supply large amounts , too much for the hobbyist. Dont store it in sunlight, read instructions regarding skin contact etc. Is there a local hobby store, aircraft, railways ? They will stock epoxy in modeler`s size tubes. You will need cellulose thinners or acetone for cleaning too. Yes "rubber" gloves the non latex type. Good luck, keep us informed and plenty of pretty pictures of the build and your islands !
