No, professional pcb maker use spray developing only for fine structures,
6mil and down, where 6mil can be done on immersion tank.
The point is, that developing on spray method is critical, because
it needs anti foam agent and the developer don´t last long.
For 10mil and 8mil, the immersion tank is prefered, eventually 6mil
with agitation (pump+filter, Co2, mecanical) too.
