Hope this helps!
Ok, now I am worried. I thought the wood layer was way thicker than few tenths of millimeter, so my rises might be actually in the ballpark of the thickness of the wood ...
I am not sure I understand hoe the penetrating epoxy will work. Do I need first to sand the bottom? or does the epoxy go through the paint? It would seem that the proper way to do this would be to sand the bottom (until the wood shows), put the penetrating epoxy on, sand, put fairing compound, fair and finally paint ... all this on a very large surface ... what a mess
