I do not like paste solder, in my limited experience with it, it’s
messy and hard to control. I have the idea that it is more
expensive, but I don’t know that for a fact. (I admit to having a
personal bias against paste solder.)
There is no particular reason to use paste solder with PMC. I
solder PMC all the time and never use paste. I apply solder the way
I was taught in my first apprenticeship, using sheet solder, cutting
it up into tiny pallions, and dipping each tiny pallion in a puddle
of flux, then applying the solder chip to the whatever. (The person
I worked for did a lot of intricate applique soldering with lots of
cut outs.) I usually use a tiny paintbrush.
I have found no difference btw soldering PMC+ and soldering
sterling. You’ll often hear that you should use a little more solder
with PMC because it’s more porous. And you’ll especially hear that
in regard to PMC Standard.
So, to sum up, use whatever solder and flux you normally use to
solder sterling.
