In case you're wondering how this holds up, I had the occasion to revisit the client a few weeks ago. As you can see, despite the heavy traffic of three little girls using this bathroom day in and day out, the finish has remained as pristine and new looking as the day it was done. The only maintenance required is to wipe it down with a damp cloth. No chemicals necessary!
Being so pleased with the outcome of the first vanity, I also redid the white formica vanity in the master bathroom that same year. As you can see, it also looks good as new.
