I think it can definitely be done (on most paints), but I also agree that many users "think" they have a hologram free finish when the car leaves, but I doubt they've actually gone through all the precautionary measure to make "sure" they're truly gone. I know that back in my high volume days I had cars looking perfect when they were done, only to see them later filled with hologrmas....obviously that was a long time ago, long before I found Autopia and other detailing forums, where I realized I was not as good as I thought I was.
Personally, I like to finish with a DA now ensuring my cars leave with a 100% hologram free finish, and I'll usually take that over any marginal improvement in gloss that a rotary may or may not provide. However, It really comes down to the job for me and I'll use whatever tool best yields the results I'm looking for.
