Recently I was given an old Ben Hogan Apex putter. It was full of rust and I used my Dremel tool and buffing brushes to clean it up. I am using the putter and love the way it feels. However, after each use it forms little spots of rust that I need to clean off. I have tried Putter Butter and stainless steel protectant with no success. Is there anything like an acrylic spray that might work or do I need to send the putter to you for re-chroming?
