The Jenson’s Swirly Q brush is designed for scroll striping and script lettering with enamel-based paints. For scroll striping, thinner paint is recommended. To achieve this, a slow-drying automotive reducer for thinning enamel-based paints is recommended, and it can be purchased at local autobody supply stores. The brush should be cleaned thoroughly with reducer before and after each use to maintain optimal performance. It is advised not to use lacquer thinner. The user should store the brush in mineral oil between uses for prolonged durability.
