How to Repair damaged molding

This video shows the viewer how to repair a section of damaged molding surrounding a door or window. The method shown uses WD40 and polyester resin. Firstly an undamaged section of the molding is sprayed with WD40 and then covered in resin. Once the resin has hardened the WD40 allows it to be removed and used as a mould. The mould is then sprayed with more WD40 and is filled with new resin. This is allowed to harden and then removed. The resin replica of the molding is then sanded and cut to fit. Once the molding has been replaced and repainted it is nearly impossible to distinguish from the surrounding wood. For more information and more detailed instructions, as well as a demonstration, please see the video.
