Ultima Glass & Paint Prep Elastrafoam Sponge. The Ultima Elastrofoam Block is an essential part of the Ultima Elastrofoam Paint Cleaning System which is a revolutionary replacement for automotive detailing clay products. It removes bonded contamination from paint, glass, chrome and plastic without the abrasive effects of harsh polishes or the inconvenience of detailing clay. The Ultima Elastrofoam Paint Cleaning System quickly smoothes your paint to an ultra-slick and bright finish, preparing it for polishing and sealing. The cleaner can also be used after applying Ultima Paint Guard Plus to remove bonded contamination without removing or dulling the sealant finish. Use Ultima Elastrofoam Block with Ultima Cleaning Lubricant Gel, which provides the optimum lubrication to prevent surface marring from contaminants. Ultima Elastrofoam Paint Cleaning System is a very gentle polish and may be used as often as needed to remove bonded contamination. At a minimum, use twice a year as a pre-treatment before polishing with Ultima Paint Prep Plus for best results. Keep the Elastrofoam Block clean. During use, rinse frequently in a bucket of soapy water and squeeze to remove excess water. Store in a cool, dry area. Do not allow the block to sit in the hot sun.
