Aquarium-Safe Paints

[Genix]

i need to paint two things, the back of my aquarium, and a custom built canopy.

the paint for the back of the tank has to stick to glass well and be resistant to scratching from my various pieces of equipment. this one must be a spray paint.

the paint for the canopy has to be resistant to chipping and to saltwater. maybe even non-toxic?? preferably, also a spray paint.

any ideas??
