I am assuming that you need them for a 1/4 narrow crown gun? and you want to
leave them in place?
If that is the case, you might find some help on the rec.boats.building news
group. I have heard of plastic type nails that can be left in composite
constuctions but in cases I have knowledge of the staples where removed
after they served their purpose. Anyway, try the recreational boats building
site.
