Re: Masonite replacement

[NRPollak@xxxxxxx]

Mary- regarding the replacement for a Masonite backboard- my understanding of 
perforated board is that while yes, it does allow a good deal of air 
exchange, the fabric at the perforations will act as a filter for any air 
contaminants, and you will see a pattern of accumulated grime with time 
(depending on the environment, of course).  How about using paper board or 
other hygroscopic materials to slow humidity changes?  I'm looking forward to 
hearing what others have to say about this.
