Move quickly at first to prevent problems until experience is gained. Areas which cannot be reached using the buffing wheel must be polished by hand. Apply the needed amount of compound to a clean terrycloth towel, diaper or cheesecloth. Be sure the fabric is soft and will not scratch the mold surface. Remove rings, watches or other jewelry which could scratch the mold surface.
Some people even clip their fingernails.
It may be difficult to achieve the same luster, but hand polish the surface until it resembles the areas which were machine buffed. Wipe the surface with a clean rag to remove any remaining polishing compound. Condition the surface for release following the instructions provided by the manufacturer of the release agent. If these five steps have been followed, the resulting molds will have a Class 'A' surface finish. The parts produced in them will require very little post finishing and the molds will actually last longer than poorly finished types.
