I recommend using yellow carpenter's glue. I even use yellow glue to adhere the window acetate in place on our kits. I've found that using an A-West bottle applicator makes gluing much easier. They come in five sizes. I use the white #158-35 (.035 OD and .023 ID) and the black #158-50 (.050 OD, .033 ID). Give them a try. I'm sure that you'll like them!
