Weldon #4 Acrylic Plastic Cement with Applicator Bottle - 1/4 Pint - 4oz - 16376 | DCM & TCE Free | - 1 Each

I’ve used some acrylic cement to fix some cracks in vintage light housings and to attempt to fix something else (that needs to be an air tight box, I failed). It may cause hazing though, so probably not pretty enough for your use. Look around at the product offerings, but this was was the slower-to-set version https://a.co/d/0ayHsWpt
