A touch-up spray gun is a paint gun which is specifically designed for use on smaller areas and in confined areas. Touch-up spray guns are usually very similar in design to conventional LVLP paint guns and HVLP paint guns, the only difference being that touch-up spray guns are smaller and they emit a smaller, more defined jet of paint.

Touchup spray guns are often used in the repair of minor scrapes and scuffs where it is not necessary to repaint the entire panel.
