I need to mount puck lights to glass shelves. Mounting tape & velcro won't work, the lights fall off. Ideas?
Adhesives.
Gorilla glue will hold it, but you may never get it off again.
You could try some white glue first to see if it will hold. If it does work, great. If it doesn't, the clean up is easy.
