No extra tools, just make tar flammable. It makes sense, and would make that stuff highly dangerous. It would be even better for separating ships because you not only have to worry about a bit of engine damage, but the possibility of someone chucking a flare into it. It would have to be a big enough explosion radius that you could jut tar and flame (with a flamer) on a junker, squid, or pyra. You'd have to use something like a flare or magma shot. A flare making contact with the tar cloud would ignite it, along with a ship taking any fire damage inside of it. So say a Banshee round is fired and hits a ship trying to make it's way through tar, boom.
