On a side note regarding the PCBs, the site reads in part:
"Expose with UV through negative film, develop with Sodium Bicarbonate desolved in water, and strip with liquid drano desolved in water."

I am uninitiated in Negative film and usually use positive MGChemicals boards. The way written, it is implied that the strip step takes place bewteen develop and etch.  Is this the case?
