A question for you chemical experts out there: If this question is not off topic: if it is let me know and I will stop.
I have a large amount of copper clad boards with no positive or negative devolopement solution on them.  Is there
a chem. that I can brush or spray onto these boards to turn them into boards ready for positive or negative developement type boards?

Think it's just solvent in a can. I bought some for use with toner
transfer. Had very mixed results.
