After sanding radially and laterally to 600 grit the only thing we use afterwards on our blanks is Yorkshire grit before then using Yorkshire grit microfine. This includes all our acrylic blanks as well as the wooden ones. No more soggy micromesh pads and water spot on the lathe bed. No more loose towels and such to try and combat the afore mentioned water spots. Microfine is also ideal for 'knocking back' finishes so smooth off. We use after applying our melamine laquer finish to smooth it out without removing the finish itself. We have also used it on acrylic laquer and even CA with no issues. Below is the description taken directly from Yorkshire grit website... Yorkshire grit is an abrasive paste formulated to give a fine keyed surface to your turnings, prior to applying your finish of choice. It consists of pharmaceutical grade ingredients, including mineral oil, beeswax and ultra fine grinding powders. These are then carefully blended (without the use of solvents or other strong smelling and potentially harmful chemicals) to produce a creamy abrasive paste. Yorkshire Grit acts like ‘liquid sandpaper’, reducing the scratches left by the initial dry sanding and eliminating the increasingly fine dust produced by traditional sanding at higher grits. On most woods sanding up to 240 grit is sufficient to start with our paste. The grinding powders we use are designed to break down to a finer mesh as they are used, while still maintaining a cutting edge, so as the friction reduces the mesh size of the grit it is effectively forming a finer abrasive. In comparison tests, we believe the finish is at least equivalent to 1000 grit.
