Fellow sanders and fillers,
Some months ago there was a thread on flexible sanding blocks and an
endorsement of a particular device--I remember a photo of a green block
against the fuselage side.  Not cheap, but apparently worth the price.
Unfortunately I can't find it in the archives.  Can someone please point me
towards the device, or recommend an alternative for sanding the fuselage
sides etc.

Thanks and regards,
Chris.
