How do I seal surface mount holes in the back of a flush mounted breaker panel?
An upcoming kitchen remodel has forced me to replace the filled to capacity main lug panel with 24 tandem breakers and no empty spaces to a new 40 circuit Homeline main panel that I'm using as a sub. The panel could be mounted as either flush or surface mount. I installed it as a flush mount in place of the old panel, however, I totally forgot about the fiberglass insulation in the 2x6 wall. Now you can see the tightly compressed insulation behind the panel through the surface mount holes. The 4 holes are each about the size of a nickel.
Short of pulling out the panel and re-mounting it, how do I seal these holes? The old panel was intended only for flush mount so there were no holes in the back of the can. I pulled an electrical permit with the intent of having my work inspected so I don't have issues when I look to sell in a few years. Now I just need to pass inspection!

I should probably clarify. My concern isn't so much about the holes themselves, but rather the insulation that is slightly bulging into the can through the holes. My thought is that this could be a potential fire issue.

Lack of insulation really isn't an issue. The box is in an attached garage that is fully insulated and climate controlled in FL, so loss of insulation is minimal. Why the previous owner decided to insulate the garage and hook up HVAC bewilders me.
Inspector came by today and I passed. Thanks everyone.
