What causes paint to orange peel?
Orange peel is an irregularity in the surface of a paint film resulting from the inability of the wet film to “level out” after being applied. Orange peel is caused by the rapid evaporation of the solvents either while the paint is drying or while it is being applied. It becomes more pronounced at higher temps and/or when lower humidity conditions exist. Orange peel can also happen if the aerosol paint can or airbrush is held too far away from the object being painted, when using too much thinner in an airbrush or allowing the model to dry in a spray booth with the exhaust fan on. It is usually only visible on gloss finishes. Once orange peel develops, it is necessary to remove the film and start over.
