I had a small portion of my bath vanity repainted with oil based paint due to a couple small scratches. The portion that was painted 4 days ago seems to remain "sticky". I don't know why as the entire vanity was painted 2 yrs. ago with this same paint, both times using a tiny foam roller appropriate for that paint. Also, this paint is fairly new that was made up only a couple months ago. Any thoughts? Thank You.
