The polymer used in this frame is nylon. I think most others would be either nylon or acetal. A common characteristic of these materials is that things don't tend to stick to them very easily, so that filling and painting would be particularly difficult. Another characteristic is a high resistance to abrasion, so that sanding isn't as easy and controllable as it is with other materials (filing works a little better). And a third is that they have a fairly abrupt melting point compared to other plastics, so that it's tricky to try to soften the material with heat and press it back into shape.

Which just leads back to the earlier conclusion that it's best left alone....
