I use plastic Veterinary syringes for applying yellow glue.
I get them from Atwood's in the Midwest but they should be available at feed and pet stores and the like that supply items like this.
There are several types of tips...but I like the short stub...about 3/8" or so...not curved.
I don't use any type of needle.
Makes it really easy to control the application without having to 'aim'.
Also, I use them for flushing tanks with lacquer thinner, alcohol etc etc...fuel line fits on the tip.
Flush out the glue with water and reuse them....they are about $1.00 for 4 of them...so I stock up.
Several sizes are available.
