Sanding-Before-Epoxy Survey

Hi All;

As a newbie to glass & epoxy on wood, I have read all manner of recommendations as to what condition to leave the wood before it's first glassing. And fortunately, all designers/posters seem to be reasonably successful at their glass applications. Some say 80 ROS, then 120 ROS, and to finish with a sanding board at 80 grit. Others say shape with the sanding board at 60-80 grit and finish with the ROS at 60 grit. Still others, like John Michne and his gorgeous canoe, finished at 220 grit. As many "glassers" as there are, that also seems to be the number of opinions. Do I get the feeling that as regards epoxy bonding strength, it doesn't matter all that much?

Personally, after sanding out my first hull, I liked to finish with the ROS because the sanding/shaping board (any length) leaves inevitable scars, especially those accidental swipes when transitioning to the concave regions of the hull. Also, I opted for 100grit disks for the finish, because coarser disks left fuzz. This fuzz seems to depend on the mfr of the sanding disks, yet another variable.

I glass the hull on Saturday (wish me luck) so this is my last chance to ask. Right now I have a satin 100 grit ROS finish on a sanding-board-shaped hull - what do you think, how would you have done it?

Thanks for any help, Spidey
