For those with IPA questions, IPA = Isopropyl alcohol or rubbing alcohol. All brands are the same. I get it from Target, Costco, or any pharmacy.

It is used to eliminate oils on the paint. When you use a polish or compound, it can leave behind oils that 1) hide swirls, which is not ideal when you're trying to correct the paint, and 2) it can inhibit the wax or sealant from bonding to the surface properly.

After each polishing step it is a good idea to do an IPA wipedown, which is a simple as spraying a panel and wiping it with a good microfiber. The alcohol flashes fairly quickly so it dries fast. That way you can evaluate how much correction was done. And when I am laying down a base coat of wax or sealant [not an additional layer, but the initial application], I will spray down the paint to prepare the surface.

Hope this helps!
