I tried really hard, to find anything about something traditional vehicle related to mirrored firewall on the Google box, to no avail. All I got, was computer gobbley gue stuff about protecting your computer by making a same image of something .... Would it be, that by using a polished piece of stainless metal as a firewall, to display a highly detailed engine, for use in a show car ?
A search here on the H.A.M.B., produced this borrowed image from user ---- SLAYER ---- from an August 14, 2018 post.
I tried polishing my aluminum 'wall but can't keep it glowing. Best I can maintain is bright aluminum.

@Anderson posted this ‘32 in his GNRS photos, it is Bill Aiken’s restored car. Bill, RIP, was a noted Southern hot rodder and restorer of Indy cars.
First time,I added a shiny firewall,I hand polished a alum sheet in late 1959 to my bobtailed 1928A hotrod> repolished it a lot. A number of years later I got call from a good buddy "Rosh",who I had helped build his T-bucket. The call was about some shiny sheet stainless he found were he was working! Rosh,said;"I know you love shiny stuff,so I have some shiny junk in my truck for you"! Turned out he was working @ MIA next too a full new remodel of a old artdeco building at MIA. Had ripped out a stainless steel artdeco wall{ of mirror finish SS with dimpels made to look like industrial rivets/a very artdeco thing !!!! I thought it was awesome! Trashed my hard to keep shiny alum sheet fire wall,an used the scraped SS artdeco sheet too replace it !!! The SS was very hard to cut too fit,but still love how it turned out !!!
My '34 Plymouth coupe, built in 1974+, using a stainless steel counter top from a military kitchen they were throwing away. Polished, cut and drilled (the cutting part was a bi**h!). John
Stainless is definitely the way to go for mirror. This isn't a firewall but we used a polished stainless panel in the bed of a '42 Willys pickup with polished stainless Chevy bed strips.
This is where I got my stainless, high quality and good prices, protective sheeting on both sides https://www.coremarkmetals.com/304-8-mirrored-stainless-steel-sheet
Here's a lousy pic taken from a movie called Fast Company filmed here in Edmonton. That's my 34 Ford with aluminum covered firewall in the background. Was only onscreen for seconds but they sprayed something onto the firewall so it wouldn't be so shiny. It washed off.
