Anyone know of material/technique to "tone" down the visual impact of

Smoked finish to compound the problem in the present case.

I've found a solution of waterglass (sodium silicate ?) washed into
scratches in glass, part evaporated, then cut back with a damp cloth,
in a polishing action, is useful for glass.

I seem to remember toothpaste was used by motorcyclists
to polish perspex screens. Supposed to work quite well.

I have used it in past years to polish scratches on automobile
finishes. Just be sure to get a mild abrasive toothpaste, some of the
more aggeressive ones will dull the finish, You could also try
automotive polishing compound, not rubbing compound as that is a
coarser material.
