first, let it dry and then seal with epoxy.

Another tip for high gain circuits is it is important to clean the circuit board and solder joints after the soldering is completed. A thin film of solder flux left on the conductors can make a path for electrical leakage in the high gain sections even when you cannot see the flux. It is common practice to clean the circuit boards with methylated spirits and let it dry before sealing it with coatings and potting. The cleaning of the circuit can also help when tuning the circuit so small signals are not lost with electronic noise from leakage across the conductors near the transistors.
