Hi Bob,
I agree with you. Some people on this list have made
homebrewing pcbs into a high art form, When many of us
are just hobbyists wanting to do a few boards now and
then. These "artists' look down their noses at some of
the simple methods and discourage discussion by the
newbies. (Hi Stefan) (Listowner take note)
I haven't used the Pulsar "Green Film" , but I got the
same results with some leftover gold metallic "laser
foil" and some Reynold's Parchment Paper. It's a
metallized layer on a polyester film that is grabbed
by the toner when heated. It is used for hot stamping
foil seals on material and in the early days before
inkjets, one of the few ways to add color to your
documents.
It worked well on the pcb., I think part of the
success is that it flattens out the toner and seals up
some of the pinholes.
I like your foam brush idea, I used part of a sponge.
Keep posting the simple solutions.
