Have you read that article Bobby, or better yet, used the entire method in that article?
The reason I ask is because it doesn't recommend using #7 as any kind of a temporary fix. It is using the #7 to remove most of the oxidation. Used as a top coat that you just wipe on the paint like a wax it is indeed very temporary, and results are nil, because it will just wash off.
However, when using it to feed oil back into the paint and remove the top layer of oxidation, it is a different animal.
Again, the article covers this. If you use the #7 to get the oxidation removed, use another high oil content polish, like M80. Meg's D151 has done me no good on the two single stage vehicles I have tried this on (and regularly maintain, one being my own '71 GMC, one my fathers 4-Door Dually). D151 is usually my first go to because of its ease of use. I can't say that the results are always the same though. What I have seen though is that the single stage just sucks up any oils that are in whatever polish you use, and you are just taking away your paint layer. That's why the use of #7 is almost inherent.
If you have surface defects to correct, do it after you have "oiled up the surface" and gotten the oxidation off. 151 could be used here, but I don't prefer it because I like to use a good carnauba wax after polishing SS paint. A pure polish with even more feeder oils (M80) seems to work best, for me.
I just didn't want to confuse the OP thinking that the #7 was a temporary fix OR a polish job. It is just the "pre-polish" step that really makes SS shine.
