• Molotov: 0dmg

Notes:
The flamethrower starts a fire after a burst of 13 fuel. The fire doesn't inflict damage to sheet metal doors.

Sheet metal doors share the same hitpoints and defense bonuses as the double sheet metal door and ladder hatch. They are invulnerable to fire damage, strong against hatchets, but weaker against heavy impacts like explosives, rocks, maces, and clubs compared to other items and building parts.

An alternative method to getting through a sheet metal door would be to find a weaker way in, like destroying the doorframe if it's wooden. If there's no lock on the door then you can open it and pick it up by holding the use button.

With Rust being consistently updated I haven't had the time to keep up. Some of the information may be out of date, and misses newer weapons.
