I have been doing some research into alternative methods of fixing my backglass. I'm not opposed to the Triple Thick method, but I am curious if there are other methods.

In areas outside of pinball I know of two other methods, and I'm wondering if anyone here has any thoughts about these methods/products.?

The first one, is LOCA glue, aka Liquid optically clear adhesive. This is used primarily in Cell phones to secure the glass to the LCD. It dries clear and holds well. It is cured with UV light. There are several different formulations, one drying like an all encompassing mass (pain to remove) and the other dries more like a gummy glue, which can usually be peeled and scrapped off fairly easily if issues arise. There are example videos on youtube about it. The videos are mainly focused on cell phone repair.

I have not seen any mention of using LOCA glue on a backglass online.

I have not tried it yet on the back glass, and was looking for opinions. I have the LOCA Osaka 7, the more gel like formulation.

Another direction I've been looking at is Edge gluing which is something that is used in stained glass repair and fine art restorations. If you search "stained glass edge gluing" several articles come up talking about different adhesives used. Essentially the product is applied on the edges and dries clear. Stained Glass and Backglasses are quite similar in function (art work with light passing through) so this procedure seems like an interesting direction.

I'm still gathering information and am trying to figure out how to test my theories. Any opinions would be appreciated. Thanks.

Below are some advantages of LOCA glue as listed on a wikipedia page:

LOCA has many advantages compared to traditional non-liquid film type adhesives (OCA Tape). Specifically, it:

Is suitable for application on uneven surfaces
Can be repaired and adjusted once cured
Can be used in large panels
Is completely size-independent, while OCA tape must be pre die-cut
Has high adhesion
Ideal for filling gaps because it is a liquid
Does not suffer condensation and fogging
Resists extreme temperatures
Requires less surface preparation
Is contaminant-free, resulting in improved bubble resistance in laminations exposed to high temperature and humidity
Can be applied by automated process
Accommodates thinner and lighter display designs
Facilitates faster development of new products and design

Thanks for the replies.. I'm leaning for some type of LOCA application. I would like to test it somehow.. Anyone have some ideas how to recreate peeling backglass for a test?

True.. Thank you ForceFlow.. I'm a bit uneducated regarding a show or event, but I will keep my eyes peeled. Thank you.

Great idea! Thanks!

Thank you for the info. That's partially why I'm looking at other methods. My particular backglass has some eggshell pieces that have separated but are still attached. Then a few areas that are bubbled a bit but still attached.. I'm still investigating before I shoot something on it.. Thank you!

Thanks for that link. I think it sounds very promising. I just need to figure out how to keep the paint chip flat while this is curing. I know people have used plastic wrap with triple thick. I need to do some tests. Thanks!
