Hello all. I've just got an old Moonraker interior, not the later chipboard type, but the early 70's ply sort. The wood seems to be ply with a veneer. It's damaged in a few places.Is it possible to replace it, is it the sort of job someone with zero woodworking skills can do, and lastly, what sort of varnish should I use? Is it possible to get a nice smooth finish without brush marks? Cheers.
