Weldwood contact cement is a good choice. Comes in a quart can at any
hardware store. You can brush it on with a disposable brush.
Brush on one surface and let dry, brush on opposing surface and allow to get
tacky to the point it doesn't lift when touched with fingers.
Position correctly and press to set.
The aerosol cans of trim adhesive are formulated to never dry so they can have a shelf life and be sprayed out of a can. Good for them selling glue, bad for your project.
