I put some on a rusty bolt and nut, a couple of days ago, and when first applied, it bubbled a bit then just soaked in. They came apart easily yesterday.
Another product called “Slick Stuff” was suggested, on another thread so I grabbed a can at Lowe’s the other day. Haven’t had a chance to use it yet. Looking for something to do a side by side test against Fluid Film. FWIW the Slick Stuff is about same price as Fluid Film, at Lowe’s.

Edit: You can also get Fluid Film in a gel form with brush applicator can.
