Homebrew PCBs

Checked a number of data sheets for lacquer thinner, none are or contain xylene.

My experience using lacquer thinner for non PCB purposes is that it is a more aggressive, more volatile solvent than most.  As such, I could understand why it is more effective in removing organic surface contaminants from the PCB, but as far as leaving a "good" film on the board that promotes adhesion or converting the copper to something that is better sounds suspect.  My guess is that is that it is just a better solvent or what was being used before was contaminated with something that interfered with adhesion.
