Hi
I have done a lot of testing in the past 3 weeks using all sorts of material combination to test rigidity, weight, resin usage and so on
The best 2 samples were with EasyCell75 and 3D Core

Easycell is PVC foam, so I guess I can join sheets with Solvent Cement or similar used for PVC pipes.
What can I use to join the 3D PET Core?
I'm infusing and the gabs between sheets are visible
thanks
