I'm being told that these are not widely used in USA, the common types used 
here in the UK (Peters and Electramask) not readily available, and they create 
packaging and shipping problems... thus US PCB suppliers reluctant to supply 
PCBs with peelable masking applied. Is this true?

Now they are by no means a perfect solution to protecting holes on a PCB 
during wavesolder, but am not aware of another way of doing so in a no-clean 
RoHS process if fixturing can't do it. What do US PCB assemblers do if pre-
applied peelable masking is really not viable? Other ideas?
