Ok, my little Chinooks, I give in. You win. I won't sandpaper it. Or heat- gun-blow-dry- butane-gas-with-a-match it. Well, not yet anyway... Perhaps i'll just try a little bit of sanding somewhere even I wont notice. Like under the scratchplate or on the underside, and report back. But getting sandpaper in the snow is gonna be difficult at the mo.
