If they are aluminum and you are taking them into salt water, they need to be anodized or they will quickly corrode.wetman once bubbled...
These were painted black and if you were to sand the grip down on these ones, the silver colored aluminum would be showing and very messy looking.
Its just something to be aware of.
If they ARE anodized, the coating is very tough and you will have a hard time sanding off the knurling. If you are able to, here's a couple of links to doing anodizing at home:
