I want my students to paint tin cans for making wind chimes but I don't know what paint to use.
Can I use normal poster paint and then spray them with a sealant for protecting them from the rain etc once hung outdoors?
Or is there a paint that is easy to work with (and clean up!) that will be ok in winter weather?
Ideally I would like a spray varnish in case they want to add glitter or stickers etc.
Help please....
