Bill, you may be right. He did seem very interested in doing my paint and knows that I'll probably show it some.
The sealer will be DPLF which is what he usually uses. My understanding is the re-coat time is 7 days, and that's without sanding. So he lets it cure for 2 days and sands it too. Seems like it should work well. He said it really does make a difference in a high-end job.
I can see it now...blisters on my fingers from wet-sanding.
