How to polish pearlescent acrylic

To polish this kind of acrylic, fine grit sandpapers are the best option alternating between wet and dry. Start with wet 800 grit sandpaper in a circular motion and then repeat with a dry piece of the same sandpaper. Alternate between the wet and dry pieces, rubbing for two to three minutes at a time. If it begins to look frosty this is just part of the process and these will disappear eventually. Move onto the grade 1200 paper and continue with the circular buffing motions, before drying to area fully with a soft, dry cotton cloth. If you have acrylic polish, this will help the material shine like new.
