What, you want to leave "unetched copper" on the TOP? That will short
intermittantly to ALL through-hole lead-wires, and will NEVER work! Unless you
counterbored EVERY hole with a larger-dia. drill, and then made EXTRA certain
not to push parts all the way down against the top copper before soldering on
the bottom! VERY cumbersome! Does NOT compute!
Most plain spray-paint will act as decent resist if you let it DRY, and
don't scratch it during handling. But be careful the "overspray" doesn't mess up
your resist-pattern on the other side! Better: Simply etch-AWAY all the
unneeded copper on the top side!
