Since the last question I posted about Hull Oxidation proved so sucessful I'm pushing my luck. I've attached two photos to show damage to my mast that I'd like some thoughts from you all with.
The "stripes" cannot be polished off. I've tried lots of stuff. It seems to be a removal of the anodizing if I had to guess (but I don't know much about that honestly). I don't know what caused them either....they came with the boat.
The second photo shows wear/rubbing damage at the tang from the jib halyard block. I don't know what to use to repair the damage and/or some way to prevent the reoccurance. Have any of you run across this and what can be done?

Thanks in advance......

Greg
