Adding a bit of flux (I use water based, but any flux should work) helps with reflow quite a bit. I don't do any SMT work without plenty of flux, and I typically use ROHS solder. It's a good idea to clean the flux off when you are done (I've used isopropyl alcohol, and a hair-dryer to dry it afterwords to great effect)
