The question is: how best to apply the paint to minimise texturing?

Texturing is OK under diffuse light, but is rather ruthlessly revealed
under intense projector light.

I've projected onto plain walls in the past (16mm film). Others have
mentioned similar experiences : that one thinks it's going to look awful,
but in practice it isn't a problem.

Films are rather different to projecting computer images - the latter are
more likely to have large steady areas of block colour, giving you time to
notice problems, whereas films have movement and texture of their own which
hides imperfections in the screen.
