Brush Marked Tarnish

¶ Brush Marked Tarnish. Varnish sets soon after being spread on a surface. It can be brushed and re-brushed safely if done quickly and immediately after spreading, but when brushed too much, or too long, or too late the brush marks remain. For a few minutes after spreading varnish and enamel flow out and level up the brush marks, but when they have taken a set by the evaporation of some of the volatile liquids it is harmful to do more brushing, it roughs-up the coating and leaves brush marks. The use of rubbing varnish having excessive body, producing heavy coats, causes much brushing and the brush marks may show. The varnish sets before it can be brushed out evenly.
