What kind of snaps?

I'm refinishing some helmets, and I have a couple that have snaps holding the liner in, so I'll have to drill those out. Anyone know what kind of snaps I will need to use when I put it back together. Where would I get them?


Help is much appreciated.

I would try a place that does marine upholstry. Their stuff has to stand up to salt water. It should be plated brass or stainless steel. You could try any sewing store but it probably won't be as good as the marine stuff.
