Just adding my 2c for the sake of a good discussion here,

I've used this method for finished edges of aramid cloths and its a good 
one. It's especially helpful, fast and simple for cutting off the hybrid at 
the gunwales when your done reinforcing the inside of the boat.  If you can 
glue incompletely set epoxy you get a chemical bond as strong as the resin 
if not you will find that the sanding of hybrid edges and joints will 
produce a stronger mechanical joint when some of the kevlar fibers from both 
surfaces are protruding into the glue layer. This goes a long way to prevent 
delamination failure especially at right angle joins of our narrow 1/4 inch 
thick material and sanding helps in that not only the kevlar but the 
endgrain has also been exposed or re-exposed.

I do second Bill's suggestion of covering the whole sheet of material used 
to make the CB trunk and internal bulkheads and soldiers with peelply before 
cutting out the shapes.  The lighter weight fine grained peel ply is just as 
good as the coarse woven stuff for our purpose and when the bulkheads are 
recoated with epoxy after installation, the fine woven texture that it 
leaves behind holds less epoxy on the surface.

BTW, no smoking and no drinking  either! Its much  much worse than epoxy or 
amine vapor, aramid glass or carbon dust.
