Plexiglas^® sheet can be cold formed (bent at room temperature) in a smooth arc and held to a radius by forcing the material into a curved channel support. The recommended radius of curvature should be a value greater than 180 times the thickness of the sheet for Plexiglas^® G sheet, and 300 times the thickness for Plexiglas^® MC sheet.

 A properly drilled hole has a smooth semi-matte finish that can be brought to a high polish.

• A wood or metal rod approximately 1/8 inch smaller in diameter than the drilled hole is split to a depth equal to the depth of the hole plus 1/2 inch and mounted in a drill press.
• If the inner surface of the hole is rough, steel wool or strips of emery cloth or sandpaper are wound around rod and gripped in the slot.  
• When the inner surface is smooth, a good grade of flannel is wound around the rod and the compounds for buffing are applied.
