I once had a glue gun that came with different sizes of discs the gun would melt the glue that was on the disc and you would be able to hang the disc anywhere you would like to hang things. im looking for the name of this gun due to me no longer having it. i believe the name was somewhat like "Duzit"
any clues?

Try Lowes or Home Depot. I think they have some there.
