The lens to my gauge cluster is discolored in spots. It has a white cloudy look in these spots. Someone told me that I can polish it with blue magic metal polish (I think that's what he said). Has anyone tried this or anything like it.

I've used Simichrome (sp?) and it works well. Knowing better now, I'd use plastic-specific polish like Novus.

Get some Mothers plastic polish and buff it out.. It will look like glass...

mine was extremely spotted. took out the plastic and polished it w/ toothpaste. it was midnight one night and had no "real" polish so instead of waiting till morning i just used toohpaste, worked real well.

and after

mine is exactly like that but not quite as pictured as above. I havent fixed it yet, but i was thinking about using the plstic buffing compound...its the same stuff that i used when i polished my taillights....

Thanks everyone, I had some mothers and it worked great. Looks like new, if only the rest of the car did. Paint job coming soon.
