ive heard of people doing something similar with r/c car fuel but i dont think its worth waiting for the gas to vaporize propane is probably just as good but i have never tested it myself

If you put gas in a spray bottle you can use it and it works pretty well.

I wonder how well kerosene would work. I would feel safer using that.

probably not, gas's ability about dissolving plastics seems to have been over exgerated. It will dissolve some plastics but not all, and the spry bottle should be fine.

It depends on what the spray bottle's made of, (the chemical composition). Not sure about this but past experience has told me that HDPE and gasoline don't get along.

If nothing else, you could try 91% isopropyl alcohol or denatured ethyl alcohol instead of gasoline for a fuel in a spray bottle. I use 91% alcohol quite successfully in my BS gun by adding a few drops, closing the cap, and then heating the gun with a hair dryer and shaking the chamber pennies around.
