Painting in oils
When we travel, I switch from oil based paints to water based "oils" such as those sold by Grumbacher. They work just like traditional oils yet you don't have to worry about solvents or smells or specisl handling. Easy to dispose of dirty water used to clean brushes. Drying time is the same as traditional oils as well as color strength. In the studio, I use only Gamblin oils and their solvents. No offensive smells. Excellent brand of paints.
