151 BUFFING AND POLISHING PD-1805 Caution: Wear the proper safety protection when sanding, cleaning, mixing and spraying all materials included within this process. 1 Wash vehicle with soap and water. 2 If you have some orange peel / texture, start with P600-800 grit on a block or hard pad to smooth / flatten the paint. 3 Sand only enough to take out peel then move onto P1000-1200 grit working toward P3000 grit sanding in a criss cross pattern. Sand with P1500–2000 grit. The finer you sand, the less you have to cut with a buffer. Use 3M ™ TRIZACT ™ HOOKIT ™ P3000 / P5000 foam discs on a DA to help start the buffing process. Be careful not to let paper dry. Watch for curlicues—you don't want them. Lightly sand edges and peaks with P2000- 3000 paper only. 4 Wash and dry the finish, inspecting to insure it's completely flat sanded. Begin with a wool pad and cutting compound. Keep buffer moving, bringing up a 2' x 2' area to a scratch-free shine. Then move on to the next section. Keep buff pad clean. Don't let excess compound build up and dry on the pad. Take your time. Use sufficient lighting to help see if you have a scratch-free, smooth surface. If not, stop and re-sand with P2000-3000 grit and re-polish. 5 Once the finish is buffed with sanding marks and scratches removed, wash the vehicle to remove any compound residue. Moving slowly in one 2' x 2' area at a time, machine polish with a foam pad. Don't let polish build up on the pad. Once completed, wash vehicle again to remove any polish residue. 6 Use an ultra-fine pad and ultra-fine glaze to machine work the finish. Buff by hand with a microfiber towel to a deep gloss finish.
