I think you just had it too thick.

My scheme had been to use a sprayer to get the paint in position to
brush. Now I want to try your method!

Louver door I'd just spray it, that's a good example of what
a paint sprayer is good for.

The idea of laying up the paint with a garden sprayer is
similar to what many painters do when painting rough siding
and similar. They use a paint sprayer to quickly lay the paint
on, then back brush it to work it in. I recently used that
method for the first time myself. The main advantage is that
it eliminates all the back and forth to transfer the paint from
a can to the wall. The advantage of a real sprayer vs a garden
one is it moves paint many times faster and more uniformly, better
control, etc.

But for a porch ceiling, I wouldn't spray. I'd use a roller,
back brush if needed.
