Does anyone know what the lap bolt heads (holding the lap seams together) might be bedded/puttied/covered with on the outside of the hull, 1963 Thompson Super Lancer. It's a gray, hard stuff.

In attempting to remove the nuts from inside the hull to replace the bottom, which is bolted to the last lap past the chine, all the bolts turn with the nuts, so this stuff has gotta come out.

I tried to pick it out with an awl, but I'm wondering if heat would work better.
