Edison and Dan may have to debate specifics on this one, but I agree with 
Ralph - Ellen's instincts are right. The wood has to breathe. On top of 
that, with these types of paints the building loses lots of visual 
character. If I recall correctly, the paint goes on much thicker than normal 
paint and so crisp lines are lost. We've had lots of discussions in our 
office about similar products, although I don't recall Rhino specifically 
(or Edison, for that matter). Maybe some brands are fine. While some 
historic district commissions cannot regulate paint color, they should be 
able to regulate treatment, which includes choosing a paint that will not 
cause long-term damage to the historic building. Perhaps the company could 
provide examples of its use or a sample to view. You should definitely ask 
to see its application/approval in other historic districts. And, by all 
means, make sure someone will be able to remove it in a few years when we 
all find out what the true story is.
