Review on 🔒 1lb Duct Sealing Compound by Rectorseal 81880 by Nathaniel Collins

Used this to run wires through my car's firewall where mice had eaten the soy-based plastic grommets meant to keep water out the side Car. Doesn't look pretty, but stays where it's supposed to, doesn't get your hands dirty, always stays flexible and doesn't let water through. This material was used in the Navy to plug gland tubes around bulkhead wiring to keep water and vermin out of ships. good enough for the fleet, good enough for my car.
