 YOUR key word........Leakiness. Accordion reed shoes are waxed into  
position. Unless you seal the reed shoes in somehow, there are  
literally hundreds of places to leak (every edge, in fact). Since  
harmonicas are blow AND draw and not just blow, the sealant would  
have to be chosen carefully.
