I use cheap craft paint brushes for weldwood or laminate type glues. About a # 2 I cut the end square with my serrated scissors so it holds the bristles . this gives me a glue line about 1/8 - 3/16, as mentioned above take your time it will work out. don't throw the brush away. It will get hard when it drys, however it will turn soft again when you use it again. just flatten the tip and let it dry. Brush last a long time.
