I would agree with Lloyd.  I have worked with the 3M 1904 material and like
it, but like any material, it has it's drawbacks.  Durability may be an
issue as Lloyd stated. It may not be suitable for higher voltage
applications.  The material is thin enough to not provide any appreciable
tin whisker mitigation.

On the other hand, this stuff gets everywhere efficiently.  The Novec HFE
carrier solvent takes it under parts.  The relatively soft nature of the
material, which makes it a durability concern, also means you don't have to
mask connectors.  Can serve as supplemental coating to coat those
components (like connectors) not normally coated.
