I just finished making a dosimetry phantom that started with table saw cuts and ended up optically pure. Once I got the phantom wet sanded with 1500 grit paper, I used an $8 buffing kit and a normal household drill to easily polish to a high luster. The kit had a mandrel, three cloth wheels, and some compound sticks. I used the finest compound and the kit will tell you which is for polishing plastic.
You can test by getting the kit at Home Depot and a piece of acrylic/plexiglass. Dull the surface with a fine sand paper and then try the buffing wheel to polish. Look at the ceiling light reflected in the surface and have the buffing wheel follow the light across the surface. The clarity of the reflection of the light will lead you to success.

We have thought about using one of those headlight restoration products like this one: http://www.tooltopia.com/presta-136816.aspx?utm_source=googlebase&utm_me dium=cse&utm_term=PST136816&utm_campaign=googlebase_18u&gclid=CMD4m8jlhL gCFVNo7Aod0moA6A Has anyone done this to their instruments (like a 450P, E-600, or Electra meter) and could share their experience? Other ideas?? Thanks, Rob Robert J.
