I was wondering if anyone has a good idea for filling holes in the mast. The PO over did it by installing additional hardware on the mast. When he removed them he left multiple holes that I would like to fill just to keep out bees or hornets.

I had head once about using some type of epoxy compond that is made for metal.

I'd try a rubber plug. How big are the holes?

If small enough, they can be filled with a screw or pop rivet. Big holes can be filled and refinished by a skilled aluminum welder. I pulled my C22 under a power line on it's trailer, burning holes in the mast, and a welder filled them and refinished it, making the repair invisible.

If the holes are half inch or smaller and round you can tap them and screw in a machine screw or bolt and then cut the head off the bolt and grind it flush with the mast. larger hols can be covered with an aluminum plate screwed to the mast also use a little bedding coumpound on the plate.

Go to the hardware section at Lowes and buy some plastic hole plugs.

There is a two-part epoxy called JB Weld that cures to a dark grey color. You should be able to find it in most hardware stores. It cures in about 4 hours and can be sanded flush to the mast surface. Be careful sanding or grinding on the surface of the aluminum. It is anodized for protection, and sanding will remove that protection and can lead to corrosion.

Paul,

Thanks for name of JB Weld. I will look it up. I like this idea because it will not be something for the internal halyards to catch on inside the mast.

The holes are various size bolts and screws to attach hardware to the mast.

I can second JB Weld, although I've never used it to repair a mast. Be sure the area is very clean by scrubbing it with acetone so that you get a good bond. And while the masts are anodized, minor scrapes will soon corrode to a hard surface and stop corroding unless disturbed.
