My earlier outdoors use of epoxy resin always seemed to result in degradation over time, along with discolouration, crumbling, cracking etc when exposed to direct sunlight/UV so I now stay away from it. I have used the non-acidic silicone sealants for various antenna purposes that have soldered joints but haven't used it directly on a built-up PCB. You could always apply a liberal spray coating of PCB lacquer over the PCB + components (both sides) before encapsulating it with the sealant in order to prevent any corrosion. By the way, the sealant shrinks over time so use extra.
Let us know what the outcome is as plenty of others may eventually need the same answer themselves.
