But it's the 99+% bet based on what the OP posted, especially if we're talking steel frame, aluminum post. How conventional can we get for standards? And I don't recall ever dealing with any steel frame/aluminum post issues except for wrong diameter posts ever. And slippage was never a common issue with factory bikes until CF frames. Statistically, a very good bet.
There are good practices for analyzing why a post doesn't stay put in a conventional situation. Shops all have the tools and hopefully train their mechanics to follow a checklist so they don't mis-diagnose the problem.

Some carbon gripping parts cause steel to rust.
I use this on metal posts & frames, even though it is advertised for CF parts.
It has a gritty component that improves the friction between parts so you don't need to overtighten the clamp bolt.
And yes, I would wipe out the framesaver in the area of the clamp.

Collar so I don't have to tighten post clamp so much. Vintage bikes to save frame at post clamp

And funniest part is that my ancient post he quoted is so old that I don't even use that method anymore.
I have long since switched to using a double seatpost clamp which accomplishes the same thing as adding a single clamp above it.

My new aluminum Trek came with that on the seatpost and it appears to be working.

Have a steel MTB frame, aluminum post (26.8). Even when I tighten the thing as hard as possible -- yes, I know you're not supposed to do that! -- it still slips. (I put "frame saver" in it before building it up . . . could that have anything to do with it?) I'm thinking perhaps spraying something in the seat tube, or widening that gap in the seat tube with a file. Would either of those work? Or is there something better to try?
