There's a thread over at Punkworks on TechPB's forums discussing polishing internals but unfortunately, no one has a new gun to get data from the before and after polish job. If someone has a gun that hasn't been polished yet, we would be most obliged over there to get some more user data. Here's what would be needed.

1. Chrono gun close enough to 280 fps.
2. Record 30 shots worth of paintballs with each ball's velocity written down.
3. Disassemble marker keeping all settings the same.
4. Take a picture of the receiver halves before the polish job.
5. Do the polish job and explain what method you used.
6. Take a picture of the receiver halves showing how it looks after the polish job.
7. Reassemble gun with original settings.
8. Record 30 more shots with each ball's velocity recorded.
(9, 10, 11. For those with a regulator, turn down PSI to get velocity close to 280 and record data again.)

Basically, we're just looking for hard data that shows how a polish job can change a marker's consistency through both the ball's velocity change and the pressure difference.

If you have access to programs like Excel, you can also show the mean velocity and the standard deviations with the AVERAGE and STDEV functions. If not, we can do it for you if you show the velocity data.

Once you're done, I would suggest posting the data and pics in both here and in the Punkworks' thread.
