POR 15 for Anchor Chain

I love POR 15 for car. It is a stable in my garage for years. It works like magic. But not sure how that works in the submerged environment. Anyone have experience with it?

Re: POR 15 for Anchor Chain

Ask them how it performs with continuous submersion in salt water. I suspect they'll say "not intended for that use".

OTOH you can still buy cold zinc paint, and repaint with that. But if you can find someplace to do a hot dip, that's still supposed to be the most effective and cheapest solution long term.

Re: POR 15 for Anchor Chain

Sounds like an interesting idea. And, I wonder if it would mark the deck (rub off)?

No, I don't think so. When apply to rust, POR15 forms a chemical bond to the rust and yields quite durable hard finish. However POR15 is not UV stable, so you have to put a top coat on it.

POR15 comes with black and silver colors.

Re: POR 15 for Anchor Chain

I'm a big fan of POR-15 for stuff in the engine room, etc, but I wouldn't bother with it for anchor chain.

I've used it to tidy up a few of rust spots that periodically surface on my Manson anchor, and after a few months of use, it looked no different than before...

Re: POR 15 for Anchor Chain

For the amount you'll spend on POR treating, then repainting...dealing with all the hassle, just buy new chain. POR is expensive stuff. $50 a quart. How many quarts are you going to go through for 100-200 feet of chain.

Free freight, new chain. Try to sell your old chain for salvage value. You could probably get $100-$150 for it.

Defender is cheaper, but shipping something like this kills the "deal"

Would that even be a problem? Most of the chain would be either in the locker or under the water.

Re: POR 15 for Anchor Chain

The only thing one can do with rusty anchor chain is hot dip galvanizing. No paint can stay on chain when it drags over the bottom as the boat swings, even on a sandy bottom.
We bought US hot dip galvanized chain in November and it is already beginning to rust, so even that isn't as good as it used to be. Of course, we use our chain every day, but still, I used to get 5 years plus on US chain, under the same conditions in the 70's. Might as well get Chinese chain for the difference in price, because it can't be worse than this stuff.

Re: POR 15 for Anchor Chain

just drag the chain on the beach behind a quad...then use cheap galv paint...jejeje

no paint job is worth it on anchor chain other than for depth markers when scoping out
