I was trying to get some aliphatic resin into a tight spot today, the bottle nozzle was just too fat. Suddenly I had an idea. I have some hypodermic syringes lying around ( I use them to re ink my printer cartriges honest!) I put some glue into one of these and it worked a treat. I can put just enough glue into the exact spot I need it. When I am not using it I put the needle into a bit of cork and it is all sealed up and ready for next time.
