Jamie: There are two primary categories of peelable mask;latex and 
vinyl.The latex materials I'm aware of do not lend themselves well to 
application using screening techniques.They are typically applied using a 
dispense nozzle.The vinyls can be applied by either screening or dispense 
nozzle.									     
  The material cost of the vinyl is roughly 2X that of the latex.            
  The vinyl has better heat resistance than the latex,however both stand up 
to flowsolder quiet well.						     
  Removal after assembly can be difficult and labor intensive. If the 
material is not applied in a wide enough strip or thickness or cured properly 
it tears when being peeled off.						     
  If you decide to go with the latex style make sure you use a non-ammoniated 
version.
