Micheal: W. R. Grace has a product called M-7200 Peelable Mask. It is used to protect surfaces though the HASL process. For more information call Mark Edson at 1-800-232-6100. When using the product pay close attention to application thickness. Most peelable masks will become brittle and non peelable if they are applied too thin. Another trick I have seen used with the M-7200 is to peel it while the panel is still warm. This makes the peeling process much easier. Hope this is helpful.
