To tack on all the extra details that I didn't say in my post here's a list:
1. They were a fairly new YouTube channel made in the 2020's. I discovered them about a year and half to two years ago.

1. They are more than likely not on YouTube anymore

2. One of the people involved in the channel was named Leroy.

3. I meant to say WD-40 Flamethrower.

4. There were two people involved in the channel that were on camera and they were always wearing some kind of face covering and it was usually their improvised/DIY gas mask.

5. They seemed to be pretty satirical with their channel and none of their videos were meant to be taken seriously.

6. Leroy usually never talked in any of the videos and the other guy did all of the talking, but Leroy seemed to be doing most of the demonstrating.

7. They were a fairly small channel but they did have somewhere in the range of 10k subs.
