I have a few 1/24 cars I restored in my teens that had painted glass, not quite so sophisticated then, I rubbed them down with 240 grit wet and dry, then brush painted a heavy coat of Humbrol varnish. They didn't look too bad, kind of gave them a factory bronze tint quality. I've seen the Future technique promoted for when there is a need to sand down defects in Aircraft canopies too

i believe dipping is better than painting, in regards to future and clear parts.... but yours looks good anyway.
