I can't find reflecive lenses

[Sulla]

I am puting together a halloween costume and need to find some lenses to either replace or cover the existing lenses of the following gas mask I bought.:

I am looking for something reflective and "silvery".

Any ideas?

Fastest and cheapest method is going to be automotive window tint. Check places like strauss or pep boys. They'll most likely carry silvered window tint.
