I’ve just held a straight edge over it and it’s not quite flat.
I was tempted to try it anyway but I might as well give myself the best possible start.
I’ve seen some silicone carbide sandpaper on eBay and I’ve got a flat piece of glass, will the sandpaper do the job? Or am I better with the powder?
