    That's what I would do. Get the POWDER formula, not the liquid. And mix it so that it's more of a paste. Even better, mix it with lemon juice instead of water, and apply it hot.

    It won't truly passivate, the the oxalic acid does a good job of removing the oxide, and if done well enough, the steel should passivate itself in the open air. That is unless you're in a marine environment where 316 would have been more appropriate than 304 which doesn't deal as well with the salt air.
