<p>I agree with that. I have my beam blocks varnished so they can be inspected because a paint surface can hide other problems. One of them needs doing now...ropes are easy also.</p>

<p>Hey Robert,</p>
<p>thanks for the input. I have been concerned about the weight of the mast. I’m slightly over 100 pounds as is and I still have to add the crane, shoulders and final paint.</p>

<p>I would avoid adding any extra weight aloft unless it is called for in the design. Hopefully the mast is strong enough when built as the designer intended. An epoxy primer and three coats of a two-part LPU paint should provide adequate abrasion protection. A mast isn’t normally subject to the kind of abuse that decks and topsides get. I suppose you could add localized abrasion protection in places where it might be useful—around blocks and winches, for example. </p>
