Jonte, I should have added that you should check that you choose a tin/lead (SN/PB) or lead free (SN only) paste to match whatever solder you are using already. Things can get a bit messy if you start mixing the two types. Most people seem to stick with the "traditional" tin/lead (SN/PB) combination. Also watch out for some of the entries on Ebay, where they are actually selling flux only, but the wording can read as though it is actually solder paste. Jim.
