So I picked up a Bally Hardbody that had it's backglass stored in a barn. The rest of the game was pretty nice, but the translite and especially, the mirrored backglass were pretty much toast.
I purchased some mirrored window tint and went to town on it. Had to clean the remaining mirror residue off, which was harder than I had expected.
I applied the tint to the clean glass.
Put the old translite under it and trimmed the tint with a straight edge and an exacto.
Pealed the trimmed window tint away.
Overall, I'm pretty happy with the results.
