IPA is the same stuff (but at differnt %) most people have somewhere in the house - rubbing alcohol. Rub some on your skin and your skin feels cold, because the IPA is evaporationg. I just didn't know and will defer to you experts, whether a suspension of IPA and petroleum product would evaporate faster than the petroleum product alone.
The IPA will seperate and evaporate very quickly at temperature. Dry gas is indeed much higher concentrations...and often just ethanol not IPA...similar effects though.
