Anchors and galvanizing are still of current interest.

OK. But better to start a new thread focused on the question at hand rather than force us to read old an old thread that may gone off topic a bit (like this one did).

I suppose it depends on whether you consider the thread to be about a particular race, which seems a side issue, or about hot dipping rusty anchors. I read the thread with interest, I have 4 or 5 anchors and chains that are rusty. I do agree anchor size is off topic, but that is not related to the newer posts.

I find it educational that hot dipping zinc is charged by the pound. Chain has a much greater surface area to cover per pound than an anchor, will use a lot more material and it will be harder to remove excess.

Given the poundage, I could buy a lot of cans of cold galvanizing compound and recoat the anchors many times for the price. Looking at it as sacrificial zinc, I'm not sure which way is better. The chain, I'd let them do it!


Here is the original title:

Galvanized Anchor Refinishing

I also found this to be educational:

Regalvanizing uses a hot dip process that can melt the lead out of some anchors, not so with Metalizing now referred to as Thermal Spray.

Thermal Spray doesn't require minimum weight as most galvanizing shops do.

Both of these recent educational posts are on topic. These new posts are the ones you seem to object to.

I accept that there may even be rules requiring new posts, but I fail to see the logic of spreading the useful information all over the place. I applaud the people who put the pricing and alternatives in a thread about re-galvanizing anchors and chain. Very helpful.
