Meltdown

Rich gets exclusive access to a manufacturing equipment warehouse and goes treasure hunting for precious metals in the equipment's old components. Meanwhile, Dave knows that catalytic converters use platinum, so he gets down and dirty crawling under every old car he can find -- until he ends up at the wrong end of a shotgun. And Diego hits up a firearms dealer in search of guns made with precious metals, and takes an unexpected turn into hunting down a man who has a supply of silver bullets.
