(April 2015) Corruption in Brazil exists on all levels of society from the top echelons of political power (as seen in the MensalÃ£o Scandal and the Operation Car Wash and the Petrobras scandals) to the smallest municipalities.
Quartz sands, which are high in silica content, are used to make glass. When quartz sands are crushed they produce particles with sharp, angular edges that are sometimes used to make sandpaper for smoothing wood. Some quartz sand is found in the form of sandstone.
Process: As you already know, it is going to take a lot to get this down to a mirror glass like smoothness and shine. The 1st step, and literally every other step from now on is sanding. Start sanding your fiberglass with some low grit 36 or 80 grit sandpaper.Always use a palm sander, or a sanding block, only use sandpaper in your hand when you can use a block. Your fingertips will unevenly supply pressure causing streaking. Sand the whole area until you get a less rough more even area to work with.nce you have a fairly spot free and smooth area, use your spot putty on the little pits and valleys. It is a really good idea to use your finger or a razor blade to go over and smooth those out. Sand again with a very high grit sand paper (400-800).
