The photopositiv spray laquer I use says to use 7g/liter NaOH at room
temperature, with time at about 1 minute.

I assume this means that you sensitize bare copper boards with this spray lacquer, for use with as the positive-photo-etching system (like the MG positive-etch boards)...?  If so, where do you get this stuff from?
