Also, "PVC Cement" is found in the hardware for sticking PVC pipes together. Is this the glue you were talking about? It's MSDS says that it contains around 70% mixed solvents (THF/MEK) and 30% PVC resin.
This got me thinking - if this is used to "glue" PVC together, then surely MEK dissolves the fillers and other junk which is used with conjunction with PVC in the pipe? The MEK would disolve the pipe gunk and the THF would dissolve the PVC. Maybe you could extract the PVC from pipe via a hot bath with MEK?

Have you considered how much large quantities of solvents would cost? Not to mention the scrutiny picking up 5 or 10 gallons of MEK would bring you. You could easily spend days and hundreds of dollars to find out that you cannot, in fact, extract clean virgin PVC from piping in the comfort of your own home. Do some research, find a company that makes PVC pipe or slabs near you, drive by there place and see if you can't just walk up to where they unload the hopper cars, and scoop some off the damn ground.

There are actually a few blue star compositions on Skylighter using it as chlorine donor, but I'm not sure what the effect would look like. I don't feel like ordering a kilo of crap for $60,-.

Dechlorane does have a little bit extra chlorine as compared so parlon(10%) or saran (5%). The real figure that counts is chlorine atoms by mass, not per molecule.
The sky is my canvas, and I have 2,113 pounds of powdered paint in the workshop.

Also, scored a free 5kg sample from a PVC resin company

It's decent when used as a supplemental donor.
If you really can't find a source of powdered PVC then look for some clear PVC tubing or preferably something made from a hard piece of clear PVC plastic.
Soft PVC, like tubing, contains plastisizers that may adversely affect your comp.

Anyone used this before? It seems to work fairly well, and the MEK is quite volatile and evaps quickly.
Have not got quantitive amounts down, just been using enough to get a copper sulfate/chloride/perc and paraffin mix into a sticky ball.
Advice and info appreciated!

It depends what risk you are willing to take. Do you enjoy working with chloroform and other similar reagents?
