My learned and esteemed colleagues,

One of our customers has requested that we conformal coat over a DOW 3145
RTV adhesive used to stake some sensitive components.  The specified coating
material is MS470-N, a urethane product.

Is this a standard practice (to coat over RTV)?  We have always conformal
coated the PCA and then staked the components using the RTV.  Our CC vendor
isn't too pleased with this request.
