Directions for use : Ensure that surface is clean & dry. The product must be evenly applied. The presence of water, dust or dirt may influence the uniformity of the treatment. When a surface is treated for the first time, we recommend testing the shiner on a corner. We suggest spreading the product using a sponge or cloth. Use the quantity that the material can absorb naturally. Let the surface dry for a couple of a minutes, then either polish manually with a cloth or steel wool or with an automatic machine.
