I have very compacted soil in my lawn, I'm going to have aeration in this fall, can I use pennington fast acting gypsum, lime with starter fertilizer

I have very compacted clay soil in my lawn, I'm going to have aeration in this coming fall, can I use pennington fast acting gypsum, lime with starter fertilizer together before overseeding? It would be greatly appreciated if you can answer my question, thanks you in advance.
Asked by: jane
That's the same condition of my front lawn and I am using this. I have applied this, tilted the soil, reapplied and re-tilted and it seems to have loosen the soil somewhat. I am re-seeding my front lawn and seeds are germinating so I am assuming this product is helping. Final verdict will come next season
