Have you tried scotchbrite? I use it on my thermoplastics. Cant say I have experience with thermosens. Pumice substitute may help too.

they are coarse minis for a HP or use on lathe slow speed, there is also medium and fine. those may help. Again I do not have experience with the material I just have had a good experience with my thermoplastics with these and now use them to prepolish my dentures.

Is that a Nesbit partial? I would be nervous about swallowing it.

Is the retention with the full acrylic partial better than cast metal frame?

All the materials have negative and positive points so it depends the case, to choose the correct prostheses. (rx ????)

Sounds painful. I've done a couple of thermosens, a lot of FRS, and modified the odd Valplast. Thermosens and FRS are easier to work with FYI.

Get the right burr firstly.

. Then use silicon burrs, rough then the smooth to remove burr marks. Then I use resilience and mop to finish, but brush also good. A high polish is unrealistic, but a nice shine can be achieved with brasso (cream to polish brass) but I'm sure there are other options

Timeframe to finish is similar to acrylic, a little longer, but not much.
