So42ds keel

[gosportbluemist]

Hello. We had an issue on a morning where the chain rubbed across the front of the keel. We now have 6" of chiped paint, you can see the mettle. What would be the best way to repair this? I ha e a few ideas but wanted to ask for advice.

Many thanks

Sand and/or grind down to bright metal. Fair as necessary using epoxy thickened with microbaloons (tiny glass beads). Several coats of epoxy barrier paint. Follow up with the manufacturer-specified number of coats of bottom paint you use.

I'm sure others will give you more detail, but that's it in a nutshell. But it will be important to take care of this, because your iron keel will rust mightily if you don't.

Thanks. This is what I was thinking. But should I use some.sort of rust product as it will have been I the water for a couple if months

Lots of choice with paint manufacturers, choose a system and stick with one manufacturer if the system is comprised of different paints e.g. primer, and then the barrier coat, to ensure compatibility.
One key tip, having sanded ( mechanically ) to bright metal, get the first coat on ASAP, as the oxidisation process starts very quickly, so ideally paint first coat on in under an hour from grinding and sanding, (perhaps a bit longer in hot dry sunny weather) this will help the repair last. And also if using foam rollers you might find they dissolve with the pain solvents ! best use woolly rollers.

Add to first repair how too.....

Sand or wire brush the keel where any rust has formed. Then IIRC use thinner or acetone to clean the iron when prepped clean and shiny. Then put a galvinized coating on the iron, like Pettit "Rust lock". "THEN" do what Don mentioned.
Also as noted, try to use the same brand of product that is already on the keel. Not an absolute mandate mind you.
Your not the first to do this.
