[TCML] Polishing Lexan (small, recessed areas)

[McCauley, Daniel H]

Need some expert opinions on polishing lexan.
Basically, i'm looking to polish small recessed pockets that have been
machined into blocks of lexan.  For example, a 2"x2" pocket, 0.5" deep.

Not too keen about flame polishing, especially on a part that will take
a long time to machine.  Although i have read that MEK solvent is
something frequently used or a plastic polishing compound such as NOVUS.

Any thoughts?
Thanks

Dan
