There's a lot of good topics on the old forum.  Do a search on frost.

In the old days, real glass was frosted by the application of an acid. More recently, it is sand-blasted.
However today, Rust-O-Leum and Krylon (and probably others) make specific glass-frosting sprays in cans,
which will work on real glass and acrylic.

Try a Lowes near you: they will carry it.

The Krylon and Rustoleum products will be no better than the original S2000 frosts used. Many times, while cleaning glass, stars or lines are "drifted", just with the use if Windex. I'm not so sure it was acid based etch..if it was, I shouldn't have been able to move it around on the glass??? It was def an overlay of some kind.

In the past, members have found frosting the glass from the backside to be an acceptable an durable replacement method...

Precisely. If you only want to reproduce the frosted coating used on high-volume products like slot machines, use one of the
sprays; if the material is acrylic, spray is the only thing you can do.  And yes, back-surface spraying will last longer as it is less likely to be scratched or abraded; but will not look quite
as nice as front-side.

Flouride-based acid etching was used for fine work (glass cabinets, bar mirrors, even quality gin bottles) for more than a hundred years, up through the 1930's;
and is still used today for quality work. Postwar, sand-blasting is more common because it is easier to create detailed artwork, and the process permits varying levels of
"frostiness."  If you want to do real genuine quality glass frosting yourself, buy a product called Armour Glass Etch Cream. Alternatively, there will be a decorative sandblaster
in virtually every large city.

No offense to your glass blasting/etching, but I would not attempt this on anything that was not cheaply replaced....IGT didn't do it for a reason, most likely cost, but unless you are quite experienced (which you may be) I would not advise it unless I had a backup glass. Maybe try on a junk piece of glass first????

What I do is clean all the frosting off the front of the glass. Clean the back side really good and use spray frosting on the back side. This I have used on titles like Crystal Sevens, Triple Double Stars, and any that the frosting was coming off on. I use Valspar interior frosting, works excellent. Have purchased the frosting spray at Lowes. Spray several coats on letting each dry. Good luck

I sprayed some pieces on the back and was very pleased. Plus, I liked knowing it wouldn't come off. I just used whatever the local hardware store had, as we're 25-40 min from a Lowes or HomeDepot. For 50 cents worth of paint and 5 minutes of my time, I was impressed!

I have used this on my Triple Butterfly sevens, and triple stars glass, and it works great!

The $5.00 a can of Frost at Home Depot or Lowel's will do the trick.
I clean the back of the glass off and make a pattern out of plain newspaper or copy paper.
Spray on on the back of the glass. I only spray what I need to cover. When doing this you should be able to blend the two areas together to make it look factory fresh.
Do not be in a hurry! Let the Frost Dry and install back into the machine for effect.

It should only take two or three application to get the effect you may want. I always leave the Frost on the Front glass alone. When finished the front side and back side will blend together when the lights are turned on.
Some members spray the complete back side. Please remember when one does that the entire piece may come out a little darker than expected.
I hope this may help out some of our newer members.
New Life Games have been a Blessing to me & others.
thank You.

Yes, The back-side method is a good method and old fix.  The frosting on glass from factory-igt is very prone to getting rubbed,scrapped etc.. However some years back I did restore a few sheets using simple glue and white glitter.  The sheet was prepped by scrapping the damaged stuff off, if not all of it and re-frosting.  For orginality reasons this was done, not practical in a real world of useage. Having 3 women/girls in household at times has an advantage from their creative/craft skills!--- :Tongue_Out: .
