I posted this Sat. but being a noob to this forum am not sure it went through so let me apologize in advance if this is a double posting. Despite my requests to protect my new tub at all costs.... my contractor and workmen did NOT protect my tub... I have fine grit on all flat surfaces of my new air/jacuzzi tub and some chips and scratches. Can anybody advise what the best way is to repair these? Thanks.
