Stop in for a cup of coffee

Fill me in on my RM43? It seems to work eventually, but I am trying to kill everything in my gravel shooting bays. I would use napalm but I am having some application issues.
Flame actually is pretty effective.
Old school burner - just not with the jelly!
With some pressure they shoot out a pretty good stream of fuel although I don't think that's how they are supposed to be used.
We were supposed to be removing paint but thats a longer story.
