Hi Mike:
I have never had mush luck with the "appliator things". I doa couple things. for larger doses, I put some glue on a paint jar lid and apply with a toothpick. Forsmaller and finer, i used a no. 11 blade- dull works fine and apply a thin line. For single dots, I use a small piece of wire. Any of them get gunked up, i have cheap replacements
