I have a Little Joe that has some flaking issues and was in HOBBY LOBBY and came across
a package of 8X10 colored acetate sheets in 4 colors Red, Green, Yellow and Blue for like 5 bucks.
The Bally Little Joe in my back glass was nearly gone and faded showing bare bulbs
I used a set of xacto blades and carefuly scraped off the balance of faded red that was left and taped a piece of the red acetate
over it and it looks pretty good, better than it did. 2 layers of red looks even better.
Just passing it along for those who may want to try
