That's really rather cheap, compared to the usual prices for SMD paste
sold in syringes.
I'm not sure about the smd at the same time, you want to wash off the
paste that was painted on the etched parts after reflow. So if you already
have SMDs there it might be impossible to get it out from under them. With
the smaller parts it would probably wick away, but with the larger ones
probably not. Anyway you need to make larger "mounds" on the smd pads, so
you don't really add work if you make it in two stages.
What i currently wonder about is component legend. Not sure if i can
transfer on solder, but i guess so.
