How do I fix white desk after using oil based polyurethane?
I painted a desk white using Rust-Oleum chalky smooth finish Linen white. I added 3 coats of varathane oil based polyurethane to protect the paint. I now notice a slight yellow to the white paint. Is it going to get more yellow over time? Can I just sand top coat and paint the white paint over top to finish without adding a top coat? Or should I just let it be?
