Ben, these cranks arrived this morning - cheers pal, well pleased. I now face the same problem as you though - what to do so I can see my face in them??!!
I've used paintstripper and steel wool to remove a large part of the black paint, then taken more off using a rough grade of sandpaper. The main bit I'm struggling with is the rear of the spider. What have others used to get into all the tricky tight corners?
