Mike:
Will be doing a car soon. Honda with some pretty bad swirls. Would starting with Megs UC with an orange pad, then going to Poli-Seal with a white pad be a good idea?
The answer to your question comes down to you and your expectations for a quality finish?
Meguiar's Ultimate Compound finishes down like a polish on most paints and the "average" person looking at the difference in before and after if you buff out a neglected, swirled-out finish would be amazed.
Someone that really knows how to inspect paint might be less impressed.
The color of the car will also affect the appearance of the end results. A dark color will show everything where a light color or a light metallic finish won't show everything even if defects remain.
I teach and encourage people NOT to put show car finishes on daily drivers for friends, family and customers because they won't appreciate it and they normally don't and won't take care of it to maintain it like you give it to them. This means it will just go downhill and return to the condition it was before you worked on it.
Instead, underpromise and over deliver.
Don't promise to create a 100% swirl free finish on a daily driver.
That all said, "yes", chances are very good that using UC and following with Optimum Poli-Seal with either a polishing pad or a finishing pad will leave a beautiful finish.
The BEST thing to do would be to do a TEST SPOT, something I've been teaching people on the Internet starting in at least 1994 when I started out posting on the Usenet Newsgroups, rec.autos. misc and rec.autos.tech. (most people don't even know what this is LOL)
Read this article, it explains what and why... make it a "Best Practice" that you use for EVERY car you've never previously buffed out and thus have no idea how the paint will react.
