Paint or varnish is applied to the exterior of elongate elements such as pencils, by passing the pencils(3) through a receptacle(12) containing the paint or varnish(13), causing the pencils(3) to leave the receptacle(12) through a washer(17) which permits the pencils to leave the receptacle with a coating of paint or varnish on the exterior thereof, and subsequently passing the pencils through a light box(23) adapted to apply light to each point on the exterior of each pencil(3), the paint or varnish(13) comprising a resin which has the property that curing of the resin is initiated in response to the application of the light.
