How can you get rid of the pink shade out of finished paneling and make it more silver without stripping it?
You can try a glaze with a silver tone. Spraying very light coats might tone your paneling with a silver hue.
If a glaze doesn't work then stripping and starting over is the only way. If it has some kind of stain this will be difficult as stains are hard to remove.
I assume the pink shade is a stain. But it could be a tinted lacquer. "Make it more silver" will take some experimenting.
