I took a punt on some solder paste from Ebay which is considerably cheaper than the "No Clean" syringes which have been available from some UK model railway suppliers for a few years now. I've been using it for the last day or two and it works very well.
I got mine from a UK supplier because I wanted to get it fairly quickly so I had to pay a bit more for it
MECHANIC MCN-300 Liquid Solder Paste BGA SMD SMT Sn63/Pb37 leaded.
...although I note that his price has gone up by £2 since the beginning of the week.
However, if you want to wait a bit longer, you can get it from the Far East for a lot less.

...although this advert doesn't state how much is in the jar - the one from the UK source holds 42gm.
It is the "usual" 60/40 tin/lead mix with a small amount of silver added so it does run well when molten. The paste is quite soft and I am applying it with a cocktail stick but it might be possible to decant it into a syringe. I'm storing it in the fridge to get the longest shelf life but I suspect that I will never be doing enough soldering with it to use it all before it goes too hard to use properly.
I've been finding that I've been tending to use too much paste if I want a nice clean join with no excess solder around it so I suspect that I'll be using even less. I've been using it with my RSU but I expect it to work equally well with the soldering iron.
