covering turning yellow
Hi guys, I have a covering problem which someone has an answer to. I covered a wing panel with Nelson Color Fab white [ an excellet material to work with] and sealed it with Minwax fast drying Polyurethane . After drying the covering has turned slightly yellow. I could live with it over a colored section but over white it stands out like a sour thumb. The problem is how to remove the urethane so that a different sealer could be used. I tried lacquer thinner also acetone neither seem to work. The last resort is to remove the covering and recover. I really dont want to do this as you all know what a pain this would be. Suggestions welcome Thx BOB D.
