I think it would be easier to make a convex cabinet scraper than a plane (someone posted a link to good info on making/sharpening scrapers a while back - search the archives). Also, wipe your boat with a wet cloth prior to your seal coat - any glue residue that needs additional sanding/scraping will be obvious (as it is now under your epoxy). The water will raise the grain, so finish sand the entire boat lightly, the bad spots heavily, and seal. I'm just starting my first strip building project (a canoe), so these are just standard woodworking tips, but I think they apply.
