A pretty  good article about CA glue.  Moisture is required for a cure.

You still have expansion and contraction due to the temperature.  

Sorry, I didn't consider them.  Not that they're significant in this context.

The Wood Handbook pertaining to temperature and  dimension. https://www.fpl.fs.fed.us/documnts/fplgt...gtr113.htm  A great resource for experimentally valid data.

I don't consider either to be flawed.

Thanks for all the info.  I picked up a tube of E6000, I think it will work prefect for what I need.

The OP said 1/8” ply.
I doubt you’ll rabbit it.

E6000.

I missed that.

He could put it between two pieces of wood tho and seal around the edges

Brush on some Elmers white glue, press and squeeze it out- seal the sides.

I've done it on a smaller scale- But if your project is larger and the ply expands more or less than the plastic (and it will), it could cause problems.

It would be better free floating.

I am thinking any white or yellow glue is bad for the outside elements.

 He said it would be outside but not in the weather. As long as it is sealed around the edges and not in the rain, it won't get wet. White Elmers turns into a clear hard rubbery film when dry as you know and makes a great film between glass and plastics.
