Hi,
So we are building a cyclorama (infinity screen)  and have a pro coming in to lay a resin floor. The walls and curves are made with 9mm ply and MDF. We plan to line the wall with 30gsm tissue glass fibre.
The wall are 4m high and we have a total wall length of 21m.
Should we be using The same gel coat or a laminate epoxy?
Can you apply either using a wagner spray gun? And if so how would you clean it before it sets?

Any and all advice welcome
