Is there a product similar to the stainless steel film but is mirror?

Hi Linda yes there is, and it is usually in the automotive section. but you can find it online and likely in the same sections as mac tack and other decor type decals, long story short, yes it is out there.

Hello Linda,

Yes, Mirror on a roll. Sticky back. Available Craft shops and DIY stores, maybe Auto shops. Best wishes. PS. You can get it from Window film suppliers too!

I'm not sure what you'll be putting it on, but Krylon and Rustoleum make a mirror glass spray paint.

I think thiis is what you are looking for...this explains how to install it.

Yes! Mirror film. I would ask at your local hardware store.

Do you just need a spray paint like this? https://amzn.to/3cLlkCK
