Did a little heat gun restoration on some rather rough interior plastic I grabbed from the salvage yard.
Quite far from perfect, but considering these had likely spent many years exposed to the heat, sun, and elements, and I am pleased with the results. One example below.

Final photo accentuates the remaining scratches; looks even better in person. Still very clearly not new from the factory, but not too shabby at all for a piece of plastic that has lived a very rough life, in my opinion.
