This is for a rental unit, so I’m trying to keep the cost low, while also sealing it away from silverfish. I have very fine steel wool on hand as well as a tube of DAP ultra clear flexible all purpose sealant.

    If I’m being a cheap ass but also worried about fire I would get fire resistant big stuff and fill it up. may have to wait till one layer cures to close the gap enough for a second layer and then cut some sheet metal and make a crappy escutcheon type of thing to slap on top of it and call it a day
