RB406 is good stuff for sanding epoxy, I agree. I also happen to prefer hand sanding to using power tools most of the time, goodness knows why.
BTW, these people:
http://www.ccabrasives.com/woodturners-100mm-j-flex-cloth-rolls-88-c.asp are pretty good and a fair bit cheaper than Axminster Tools. Although the latter company are pretty good they do tend to add a fairly hefty markup on a lot of the stuff they sell and it pays to shop around. My current bench lathe is a good example. It is the same generic Chinese model that Axminster sell for well over £900, yet which is widely available for less than £600.
