Yes, wraper. The result I have is closer to what they show in the PDF as "Current technology" than the shiny "GC 10" shown next to it. It may be completely fine, I do not know. I haven't run a batch in a while but if memory serves me correctly, joints were shinier after having been retouched with a soldering station.
Just did a quick check and the GC10 received in April from Farnell expires mid-October 2016. Might be related, I don't know.
Anyway, Galden and GC10 made the whole process a breeze.
