My keel bolts look nice and solid, no issues with the keel... but i'd like to take the bit of rust off down to clean metal. Is this a rather dumb idea... and if its not, and I used a wire brush on a battery operated drill, am I going to tear up the bolts doing it? a bit concerned as I don't want to screw up something that is currently not a problem.
cheers

Our keel bolts had mild rust. I cleaned them by hand with a wire brush and painted them with Rustoleum galvanizer paint. The coating has lasted three years with no additional rust

Tafika has the right idea. If you are addicted to power tools, use a brass brush as it will do minimum damage to the nut and bolt end. Do not coat the bolts with fiberglass. There is a good chance that you will get moisture under the fiberglass which will do more damage through rusting.

Had a surveyor on board last October. One of his observations was that we needed to clean and paint the keel bolts. He suggested just a clean with a hand wire brush and then a paint like Hammerite. We plan to do this in May when we return to Affinity.

If you paint the bolt threads then it makes removing the nuts more difficult. In that case it is better to coat the bolts with lanocote as it will not foul the threads but will provide corrosion protection. If the only thing exposed is a bolt head, then just painting it should be fine. |

A little rust inhibitor paint is not going to get in the way of a two foot torque wrench - which is what you are going to need to reset the nuts properly if you loosen them off or just want to cinch them up tighter.

Perhaps not, but if you over-coat it a few times the threads will get clogged up. It doesn't take a lot for a nut to bind on painted threads, and you'd be a fool to try and remove the nut before cleaning the paint off the bolt. Finesse is better than brute force. |
