Are you kidding or serious?

Very good ideas.

BTW, although paint (even 2-part epoxy) wears off, I liked painting my anchor because it helped to shed nasty mud nice and easily. Plus it looked cooler than galvanized.

The more I look into this idea, the better I like the it as many of the most glaring areas of rust are due to nicks and gouges where spot treatment might just do the trick. Being able to lay down some Zinc on these areas and restore the protection might be a good solution.

Thanks for the suggestion.

Iím sure he knows where all the local galvanizers are.
Heís right down the street from you.

But the heat may be too much for the lead.

You could try some POR-15. Iíve used it 5-6 times but donít recall using it in an abrasive enviro. If you get it pay close attention to the instructions for re-sealing the can.
I had a very enlightening and interesting conversation with Chris. Thank you for the suggestion.

He suggested I contact Spade & so have an email out to them to see what they suggest.

Touching up galvanized gear with new zinc has been going on since torches were invented. I've been doing it since the 1960s.

I've looked on Amazon & all I see are aluminum / Zinc Rods. Do you have a link to the pure Zinc or are these the ones you recommend?

If it isn't written about in a recent boating magazine by some prolific writer or addressed by ABYC....it doesn't exist to most boaters.

Anybody powder coated their anchor?
In the past there was a time when powder coating propellers was somewhat popular. Powder Coaters came to the boat shows but obviously PC props faded out.
But for anchors that have low temp stuff like lead PC would not be an option. 400f is just too hot.
I’ve modified anchors w J-B Weld applied in places so galvanizing or PC is no option for them either.

But the vast majority of anchors are 100% steel.
Any anchor coating would need very good adhesion and abrasion resistance. I think PC would be viable and perhaps POR-15. Anybody done it ... either?

I'd think POR or other epoxy or paint would make sense, as it could be touched up easily or have extra coats added to keep up with wear. Powder coat doesn't have that luxury.

rslifkin,
Could you be more detailed about powder coating shortcomings?

I'd expect it to work well until it wears enough to need a new coat. But unlike paint, you can't just touch it up or add a coat every few months to stay ahead of wear. So it might not end up with much advantage in the long run depending on cost of coating.

Get your chain done as well

Paint would wear off in a week for us.

Our chain and anchor rust if out of the water for 24 hours, but as soon as its all back in the sand it all comes up shiney again.

Even if one had the anchor re-galvanized it would likely still suffer gouges and damage to the surface and your method makes more sense than repainting the whole anchor. Your method would allow repair of the deeper and worst rust points on an intermittent as needed basis.

The part I question is your ability to heat the anchor hot enough to melt the zinc with propane. Sounds alot like you are repeating internet BS to me. Maybe you have a video or two to support your position. I love places like this... One's ability to type somehow makes them an expert.

More criticism by this member directed at a fellow member. Not mere disagreement with another member but nastiness and a belief in self superiority woven in. Very disappointing.
You should know TF has an over arching "Be Nice" Rule. If you can observe that you will be much more welcome. It may be hope over experience but I hope you can.

GH41,

Just because you don't understand or can't comprehend that zinc has a low melting point, doesn't make it untrue.

You can melt the zinc out of a penny with needle nose pliers and a regular gas stove.

Propane and oxygen are used to cut and melt steel, although Iíve only used acetylene. So I assume you would use these in a stick welder, not with a Home Depot propane brazer.

BTW, Iíve always found Lepkeís comment and advice valuable. The guy know his sht, especially when it comes to those lovely ole Jimmies

Zinc has a low melting point
So does solder.

You can melt solder onto wires but it won't stick to the wires unless the wire's are at the proper temp
I suspect that the anchor may need to be at a certain temp before zinc sticks effectively.
