End grain joints are the weakest, so anything you can do to improve on this would be good. I read an epoxy comparison done in Wood or Fine Homebuilding magazine a few years back, and if I remember correctly, their advice was to use it as cut off by the saw, rather than "polishing" the ends with a sander. If you need to sand the angle to perfection, I'd at least use some coarse sandpaper. I used a lot of 50 grit building N56ML, and some floor sanding belts that were something like 18 grit that looked like small gravel stuck to the paper for serious wood removal. It makes for quick work, and they remove a lot of wood during their long life. Mark Langford, Harvest, AL ML at N56ML.com www.N56ML.com
