Vanity touch up
I have a 6 yr old Bertch vanity in the master bath, white, with a corinthian door (ridges). It is in dire need of a repaint as it is chipped around the edge of the drawers and the bottom and sides. I contacted the company and they can send me a touch up but I wonder if it is beyond "touching up". If I need to repaint altogether, would it be sanding, prime, and gloss? Do I need to do something different b/c of bathroom humidity? Thanks.
