I have a 1971 Grand Banks 42 Hall 289 beautiful all wooden boat the veneer in a few spots is delaminating but back in the seventies they made veneer plywood with all high quality sheets of veneer they didn't use substandard veneer on the inside of it so if you take the entire sheet off which isn't that hard to do once you start popping it it'll just peel all off I found a little putty knife works fine then you just send the edges you get all the old varnish or staying off of it and you don't put anything back on it you just take it rub it down you know after sanding cleaner all up get her oiled and put varnish on it you don't need to add a piece of veneer back the veneer underneath it once you sand will be damn near identical or on my grand Banks anyhow it's pretty much identical to the piece that was on top of it once I've reverse the door on the liquor cabinet that I sent a picture of you'll never be able to tell
