I quite agree.

We did get fair results when I worked at a school as a CDT tech. We sprayed
the boards then spun them, this evened out the spray. (beware spinning
boards are very sharp and deadly, notwithstanding the spray of the photo
resist from the sides of the board.!)

Did the job for cheap and happy boards to show the students how to make
their own pcbs.
