Any product which won't tarnish the surface?

Got a pair of specs which have a painted coating, and the paint's fairly well chipped, so I thought I'd strip 'em back to the polished metal to see what they looked like – if appealing, I'll keep 'em that way; if not, I'll prime and coat 'em again.

I ask 'cos any metal I've seen stripped of paint before is perhaps a car roof/bonnet after an act of vandalism, and it doesn't look too shiny then!

If anyone could advise, that'd be grand, thanks.

Heat

"strip 'em back to the polished metal"

it's unlikely to be polished underneath – you may well need to have a go at it with some duraglit or something afterwards.

Assuming you take the lenses out and the ear pieces are'n painted inside the plastic then notromors but don't put the plastic arm covers in it.

edit: careful with heat – it's thin metal and will warp.

Yeah, I'd be concerned about using heat too.
Obviously the lenses, nose-pads and arm-covers will be coming out/off beforehand.
But, where the frames are exposed just now, due to chipping, the metal has a sheen to it which led me to presume that they were 'polished',
that's all.

Thanks, so far.
