I have found this not to be the case. I mixed 40% odorless mineral spirits with 60% naptha, and it smells completely different than sxt3.0, and evaporates in seconds.
I will add varying amounts of other chemicals (toluene, isopropanol, kerosene, different oils, etc) to aid in better penetration as well is decreased evaporation rate.
