The resin on the transom yielded to the gentle persuasion of 80 grit, but it was astonishingly hard. Still it sanded off and now with some stain in place it will probably look OK when varnished. I guess also with the white paint going over onto the edge of the planks, a rudder and other things going on to distract the eye from small blemishes, it will look fine.
Suddenly I am at the point where the list of tasks is becoming manageable; Carlin supports tomorrow, then carlins can go in, hatch covers, decks, then sanding for a few weeks... Then tipped over for final coats of hull paint, gunwales, rubbing strips, a rebuild of the rudder stock, oh then.... actually still quite a list...
