Hi guys, an old client saw our kitchen sink awhile ago and just dropped off his old one a few minutes ago. I have to sand and spray and clean up the s/steel before the weather changes. (no garage or spare room) After sanding what would you suggest I seal the wood with? Is there something I can do to polish up the sink? I have to pick up my son from school and would like to get whatever material I might need at the same time.
