UV light exposure....UV exposure when developer nearly depleted etc.
Does that ring a bell?

I use Kinsten brand PCBs, so its just peel off protective cover and expose.
To expose, i sandwich the PCB between 2 glass sheets and go out in the sun. 10-15secs is all thats required.
( winter really stuffs up this method tho
)
For developer, the Kinsten pack has an instruction manual
so you make a new brew every time.
IIRC, draino worked quite well as a backup to the "purchased" developer crystals.
