Plywood mill marks
Posted by mlamoreau on Aug 9, 2007
I am continuing on building my MC13 and have completed gluing the inside bow and stern. Before doing the cockpit I wanted to do a final sand of the surface. On the 6mm plywood bottom is a series of what appear to be milling marks from the plywood factory. I have tried sanding them out with no luck...I do not want to sand too much to get through the ply. Anyone else run into this? It is very visible when epoxy is applied.
