I've only seen blunt syringes at bigger sizes in a few places. Can you just pour VG? Or do I have to warm it up no matter what? In a double boiler?
Well, a few things. You can get blunt needles and put them on any syringe of any size (luer lock is the phrase that'll go with it)
The way I mix, and I use PG based nic in general, is to keep a small bottle, usually 30 ml, with mic base at room temperature with my flavors. I only fill from the freezer when that's empty. For you to warm up the VG nic, just leave it out for an hour, then draw up and fill your smaller bottle. Don't use a double boiler as you fight want the whole bottle of nic getting too hot, it'll just accelerate the breakdown process.
If you're in Forest Hills, there are several on or close to Queens Blvd you can get to by bus (or subway). I can look up their names if you want, one is sorta ok on juice selection the other not. Like any store they're much more expensive on hardware, and full price for juice.
