Rustins Finish Reviver is ideal if the original finish has lost its lustre or has fine surface scratches. The Finish Reviver will restore the gloss and remove minor surface defects.
Water marks and heat marks can also be removed unless they have penetrated right through the finish to the wood. If unfortunately this has happened, the only remedy is to remove the old finish completely with Strypit Paint and Varnish Stripper and re-finish.
