I am using the Glue Looper. It is an awesome tool to apply CA glue. I have used it for applying Tamiya thin glue as well.
For CA glue I place a small pool in an aluminum dish and dip the tip of the tool into the glue. Just touch the edge and the glue flows under the PE and there is no excess to be seen. Gives me a very clean looking bond. I use to use dental picks but this tool works a lot better and is very precise. Especially when glue very small PE parts.
