Rebuild and restore rotted wood without replacing it...use a polyester filler to rebuild rotted or damaged wood. You can mold and shape it to match the original wood profile. It takes paint well and won't rot.
This tip has saved my brushes many, many, times. Thanks to Laura Cox of Heart of the Home Stencils who first led me to Murphy's Oil Soap! "If you petrify a brush just soak it in Murphy's for 24 to 48 hours and it dissolves all the paint and makes it like new."
