PVA is the way to go. By far the best. You can apply it with a foam brush or a washing sponge also works. But the best way is to spray it. An other tip..Your mould is very big so you could drill a small hole, maybe in the middle where the beam is. Plug it with clay and when its time to demould use pressurised air an blow in the hole, the part will just pop up. Kämpa på!
We looked at some different methods before hand😊 but we haven’t used pva (videos are around 2 weeks after we do the actual works) we hope we’ll get the roof out of the mold once it is time to do that 😊 thanks!
As engineers, you both did well by developing a well thought out "design of experiments"..This is the only way to gain a knowledge of how the process needs to be established and how you expect the results to be.. Thomas and Petra, another job well done..
My personal past experience using Molds for creating carbon hulls/boats: we lined mold surface with sprayed gelcoat (you are using epoxy instead), finish the surface with no blemishes (it will be the visible outer surface when demolded), wax, polish, allow to dry/expell any possible solvent or additives, repeat wax stage twice more. Hulls popped out fine with a finish that required minimal extra filling/fairing. Interesting project on an engaging journey - good luck, dropping the tape idea was the right call if only because the tape ridges in the outer surface of your final piece would have sent you mad!
I'm sure the final outcome will be amazing with all these experimental tests you have done. Thanks for documenting your process, although it did not turn out as expected, for example, the test with brown packing tape. Well done. Cheers.

Thank you 😊😊
Very interesting video. Look forward to the next stage. (That’s a good selection of tyres you have in the garage!).
Thank you, so do we! 😊 (haha yes!)
Experiments are a great way to find out what works best 👍🏻

Thanks! 😊 yeah, it was definitely the right choice 😅

Thank you 😊😊
Interesting project! I'm sure it will turn out great just like the keel. Keep up the good work.
Thank you 😊 we hope it will 😊
Have you looked into using pva over the waxed surface? It‘s quit inexpensive
