Here are a few of the approximately 150 holes in the mast that required filling. The trysail track provided the majority of them - all small. The filled holes in the photo were for a winch pad to the left and for two cleats to the right. None will be remounted. I drilled out approximately 20 stainless screws that simply refused to back out. Every hole was chamfered, treated with Alumiprep, dried with hot air, filled with epoxy putty, then sanded fair with 150 grit paper (as specified for the epoxy primer).
Additionally, all of the various scrapes the mast has gotten into over the past 40 years are filled and faired. There is no corrosion aside from the shallow roughness that formed under winch pads. I think a couple of coats of high build primer will make that disappear.
Next up is an all-over RO sanding. Following that is treatment with Alumiprep and then Alodine. Priming will follow right away. I now fully understand why painting an old mast costs a small fortune.
