Brass etching is very on topic for here.

You use brass shims to apply solder paste.

Pulsar process will be better as you also
have the TRF Green layer to help block out
pinholes.  The chinese wax/plastic paper
will only have a bare toner layer.

If you want to etch brass I recommend using
photo.  Much less likely to have unsightly
pinholes come through somewhere you wanted
it all shinny and clean.

I have etched a LOT of brass in my time and
I can def. say that Pulsar with TRF is a 
giant step up from bare toner and then
photo is a leap in quality again.
