filling in holes in the mast?
 

I plan on taking off the radar dome of the mast and there will be 6 3/8" holes in the section right above the spreaders in the center on each side.

What's the best way to fill in the holes or would you leave them unfilled?

Thanks,
Gleb

Hi,
1. If the fitting was filled with machine screws, just put the screws back into the hole
2. If they were rivets, put rivets in. Aluminum ones. You could also use these for screw replacement, if it is easier, and the rivets will be less visually intrusive.
3. Thickened epoxy, sanded and painted, if looks matter that much.
Fair leads,
