Nobody needs a glue spreader, but it certainly makes the job easier. In a pinch you can use your finger, an old credit card, a popsicle stick, or an acid brush. But glue brushes are often more effective and provide more uniform results.
Rockler’s new silicone glue brush features silicone bristles on one end, and a flat spreader on the other. The beauty of this brush is that, unlike most other foam and bristle versions, it’s reusable. Dried glue peels off with ease, and the brushes are ready to go for round two.
