: I am preparing to epoxy the outside of my Coho hull, and would like to know
: if I should expect any benefit from sanding with a paper finer then the
: 120 grit called out for in the instructions. For most woodworking
: projects, I would end with 320 or 400 - why so course on the hull?

100 - 120 grit will give the epoxy something to grab on to. This is the first step of many until you get to the finer grits. Just sand a little to knock off the standing fibers (something I didn't do on my Tern) and goo it up. This is where the boat starts looking good. Enjoy
