Is the Super Tech the Walmart store brand equivalent of WD40? If so, I would avoid using it as a lubricant.
WD40 is a solvent, and will damage rubber. Good thing there's no rubber in an AK, eh? I learned not to use WD40 on drive chains or pellet rifles. On O-Ring chain, it will damage and eventually get past the o-ring, where it will dissolve the lubricant inside the chain and leave it dry, ruining the chain. On pellet rifles, it will damage seals, eventually causing a leak.
WD40 will displace water very effectively, and then dry leaving a clean surface prepped for lubricant. By itself it is not a terribly effective lubricant, and will instead remove beneficial lubricants in your gun. If you use it to clean, make certain to replace the lubricant that it removed from critical areas.
I don't have an opinion on the 3-in-1, other than I imagine it's too light to provide much benefit. It's made for sewing machines and similar delicate machinery.
