for this thers is some photoresist-like soldermask.
you spray it on, then expose it, and develop it.
I don't remember the manufacturer. i think there was one german company
but others may know where to get the stuff in your region.
how do you plan to apply your homemade epoxy mask without covering
the pads?
I always check if there is a short if i run more than one trace under a
1206 smd part.
never found one, but i rarely use smaller parts so no experience there.
