As a trained chemist, I read labels and asked my mom why she bought a rust remover spray with just this chemical (HF) in it. As a typical consumer, she didn't read the directions and ended up with some nasty burns that could have been worse if safety advocates didn't limit the strength to 1% (still to much for any consumer product, especially an aerosol spray, in my opinion). I kinda figure HF is a prescription only type item. If you can get it in stronger etching strengths, someone in that chain of distribution will lead you to this story http://www.monash.edu.au/ohs/topics/hazard-alerts/hydrofluoric-acid-fatality.html
<< cast aluminum masthead could corrode/freeze a stainless pin >>
It ended up that corrosion was not the problem. The mast and backstay took a beating from the mast on the boat next to me in a storm and the backstay made a flat spot in the center of the clevis pin and widened some of the pin. When I cut out the middle with a roto-zip cutting blade on a power drill the ends came out easily.
It destroyed the blade in the process.
Dremel would have probably worked better, but I just put the rotozip on it first.
Oh.. and as hard as that pin metal is... I can see how people cracked their topmast trying to knock them out. That ain't gonna happen, ya gotta cut them out.
Kite.. I woke up last night remembering I had told you wrong on the anchor light mounting. I edited my last desc. regarding that process.
Long story short.. I mounted the light on a new post, drilled new mounting holes that matched the old post when I removed it, and put the new post on the mast.
