I thought I would post my experience in case it was useful to someone else.
I sanded it down thoroughly and applied a coat of Zinsser BIN followed by two coats of Zinisser permawhite. I followed the instructions to the letter and 2 months later it still peels right off.
My advice to anyone...
I want to paint over some old yellowed oil-based gloss with water-based satinwood. The first room I did using Zinsser permawhite. It said on the tin that it was self-priming so I didn’t use a primer. It’s had several months to cure and I can easily scrape it off with my fingernail.
The next...
