A friend had 9 new windows installed in his home. I'm surprised the
interior window trims weren't removed, but he was considering replacing
them and I suggested simply sanding and repainting, as that's all he
wants. Only one sill is fairly bad with dog teeth marks and pits. As
long as he wants to repaint them, then sanding and repaint is the best
option, which will be done while they are still on the window.
Therefore, what are suggestions for fast completion? Using sand paper
via orbital sander or by hand with heavy to lighter grit or Using a
paint dissolving gel then scrap? Or any other option?

If this is standard trim, like you can buy at the home store I would
just replace it but I have a decent miter saw. I would still buy some
extra ;-)
