I just did this for my new stainless steel handrails. I didn't have real good luck with a bent nail so I tried various sizes of allen wrench. I found that a 3/16th or 1/8th inch drill bit through 3/8th holes at various angles worked best. I shop-vaced the chips out. After that you'll have better luck finishing up the hole with anballen wrench.
If these are new holes, you might try to avoid drilling through the bottom skin. Otherwise you'll have to tape or plug the bottom hole when you go to fill with epoxy. I wet out the hole with clear penitrating epoxy and then fill in stages with thickend epoxy. If you drill through the bottom layer you can use masking tape to plug it, then a drop or two of 10 minute epoxy in the void to seal it. That way none of the CPE or thickened epoxy leaks out. I was filling the holes in 40-50°F weather so I used the fast hardening agent. In a large flat area this would have been fine but since some of my voids were close to 3 or 4 Tbsp (or 45-60ml) this caused a thermal run away in some of the holes.
