Homebrew PCBs

Does anyone have experience with, or know of, think sheet solder mask
that has adhesive on one side?   I recall seeing a company that sold
rework equipment that sold small pieces made up for surface mount,
plccs, if I remember correctly.  You put it over the pcb, squeegie
solder paste into the holes, wipe the excess off, put the ic into the
grooves and heat it.  With something like this, even _I_ might be able
to reliably solder through-hole components!
Do any of you have any experience with this type of product for bga use?
Here is a page that does the same effect:
