As a professional luthier of 32 years, I had sought an alternative to environmentally detrimental finishes that required spraying and/or laborious wet sanding and multiple coat build up. Nothing I had tried could be applied evenly or had acceptable wear resistance. Then I found the Maloof Poly/Oil, and it has not only made my work easier, but also provided a superior finish for my instruments. There is nothing else like it on the market, and it outperforms any other poly finish by miles.
