I made some test on old orange transparent pieces I had on hand using clear modelmaking glue with great visual result, the only downside is the time it take to fully cure at core of the material.

Found this but not sure it is transparent after curing : https://www.humbrol.com/us-en/shop/adhes...ottle.html
