Gary,
I had that problem in my 2000 Marquis, and according to the boys at Beaver Coach in Bend OR. it was a problem with the sealer they were using at the time. One thing that I can tell you is that I refinished the dining table in that unit, and whatever they used on those cabinets has to be similar to whatever they used to stop the space shuttle from burning upon re-entry. I have never even seen any type of automotive finish so tough; I used every type of aircraft stripper I could find and nothing will touch that stuff. I ended up belt sanding it off with 60 grit, all the way up to 180, re-staining, and re-coating with 4 coats of automotive clear. It turned out great, but the thought of doing all the cabinets , with their recesses , what a nightmare, I would suggest if David's stuff is working at all, just keep using it.
