As opposed to the last rudder, there was very little damage to the mould this time, almost negligible as the area affected is not a part of the rudder surface.
Also, this was a couple hundred grams lighter than the last one. The reason for this is no doubt that it was manufactured with one laminating step less, ie the foam was attached to the skin in one operation, hence less epoxy needed. The finish was the same almost perfect, and a clear coat would definitely be no problem. I will paint the rudder.
