Frank S;
I use two items that I have access to so YMMV;
180 Proof Alky ( doesn't freeze, get more like syrup & chills the outside of the container during thaw), Tallow , Beef Tallow will keep pretty much like Lard will, but I have access to FREE beef fat (family down home raises "fancy" cows).
Hunting season here, so freezer is like Mary B's at near capacity due to friends' needing a place to off-load last year's dear meat (YUM).

Ditto, on the lids' insulation, mine wasn't dented but rusting. Removed it to outside for scrubbing, rust removal and painting.
Ended up replacing entire lid insulation with wool insulation ( was a recommendation from a commercial freezer repair crew). Never looked back.
Hope this helps
