Is there a reason you use etch-resist film instead of an solder mask
proper?  I had been considering getting set up for solder mask as well
as Liquid Tin for long-term protection of my boards.  I probably will
go that route (solder mask) eventually but for the short term I think
just coating with solder will do just fine.
