Magnets from a hard drive. If it's aluminum or pot metal, they won't stick.Hahaha! I can actually do a spot on perfect impression of Captain Jack Sparrow. I use it all the time. On telemarketers, usually.
Any suggestions on what I should use to mount two of these skulls on the tank, which incidentally is powdercoated? I know the powdercoating is pretty darned tough, so I don't know if I should use black silicone, JB-Weld (steel version) or clear, two-part epoxy?
(I thought about using the screw holes on the back to attach some large magnets, but that wouldn't prevent someone from stealing them....)
Gorilla glue! I swear by Gorilla tape, never tried the glue.
