I have a 1996 NACRA Inter-F-18. I store the mast overhead in my shop. This spring I noticed fuzzy salt spots on the ext. Now I have pitting.

My theory... saltwater has entered the mast cavity during capize, then the interior remained moist and corrosive.

I was thinking about drilling 2- 1/2'' holes near the base, flushing the interior with hot fresh water, drying , then coating the inside with some anti-corrision ''agent''

Might this be worthwhile or am I wasting my time.

Is a bit of corrosion pitting serious regarding the integrity of the mast.Have you fellows experienced this.

your opinions are always appreciated
