The Coleman Fuel came up from a search that I did on naphtha. Confusing results I guess.Naphtha was once described to me as "High Octane" mineral spirits. It is more flammable and evaporates faster.
I think it cleans brushes more thoroughly and leaves behind less residue than spirits. And most importantly, no longer available where I live!
I don't think Coleman Fuel is Naphtha. I think Coleman Fuel is highly refined gasoline "white gas"
