Right Guard
Note: Supposedly Right Guard has stopped using flammable propellants. You can still use a generic store brand, just make sure the propellants are flammable.
This is the infamous Right Guard. A 10 oz. can costs about $3.00. This size lasts for a long time.
The ingredients are:
SD Alcohol #40-B, Propane , Butane , Propylene Glycol, Fragrance, Isobutane , Triclosan.
Needless to say.... this stuff really works!
Right Guard is a very powerful fuel, and leaves no gummy residue like that left by hairspray. If you are using aerosol type fuel, use Right Guard. It is one of the best fuels for a spud gun.
