I was wondering, is it safe to use UV paint on a window applique? Just a FYI, the applique is on an acrylic window. It would look cool, but I was wondering if there is any danger that I should be aware of if I did decide to do this like possible damage to my window/applique. I was thinking of using this paint on this applique.

Also if it was ok to go ahead with this, can I spray some of the UV paint into a container like a plastic cup? I would need to do this as I would need to use a small brush to apply the UV paint.

yes you can put the paint on the window no you cantspray the paint in a container.
