FinalPrep is a de-agglomerated, polycrystalline alumina solution excellent for final 
polishing applications for nearly any material. With a pH of 9–9.5, the basic chemical 
element enhances microstructural features. It works exceptionally well for polishing 
soft, ductile or precious metals, and provides an excellent surface finish on many 
materials such as those listed in Table 1. 
FinalPrep should be shaken well before use to mix any settled abrasive. Since the 
abrasive can crystalize, do not let the cloth dry out. It is recommended to charge the 
cloth with sufficient FinalPrep prior to polishing to prime and saturate the cloth with 
solution so as not to polish dry. The most common dispensing parameters for FinalPrep 
are 1-second-long pulses at 10 pulses per minute. 
Before and after polishing, clean the samples with micro organic soap, rinse them with 
isopropyl alcohol and then dry them using compressed air spray or heat. This removes 
debris and abrasive particulates, and reduces the likelihood of scratches on samples due 
to abrasive contamination. After use, clean the cloth with sufficient water to remove the 
solution before storage to prolong cloth life.
