Just finishing off our new kitchen and we have a 1.5 stainless steel sink under mounted beneath granite. I almost can't bear to stick a plastic bowl in but I've never used a sink without a bowl. If we just use the sink is there anything I can use to prevent scratching? I've seen the base liners but assume the sides are likely to get scratched. This sink needs to last as long as the granite as removing it would be a pain so I need to take care of it! Thanks in advance
