Epoxy Primer on sanded metal area ! Before Epoxy it is smart to clean area with antisilicone diluent .

Blakes keel prime is excellent. Clean loose rust with wire brush and apply the keel prime exactly to the instructions. Ive been using this for years on a number of boats and it has been great. If the keel is really bad then you should get it sand blasted and epoxied.

I've just put the second coat of NeutraRust 661 on my keels this afternoon. It is a water based rust converter, and the same thing can be obtained from Screwfix Direct as "Rust Converter".
I put the 661 on my last boat 8 years ago, and looking at her recently (under new ownership) the keels have no rust showing through.
It is the same colour and consistency as double cream, but changes colour to blue/violet/black as it dries and converts the rust.
At it is water based, it can be applied under almost any weather condition - piddling with rain excepted.

Presumably, with a rust converter you don't clean the keel down to bare metal (which sounds like my kind of cure). Once you've used the rust converter, what do you then use over the top?

I have just had the bottom slurry blasted with a find mica "sand", and at the same time had them to blast clean the rust and scale from the keels. I left the keels to rust for about 6 weeks to get some rust back on them, and did them yesterday for the second time - just to built up the surface a bit and fill in some small rust voids.
As I had "clean" finish keels, I didn't need to wire brush them down again, but if the rust is thick and maybe flaky, you will have to remove some of the build up.
When I did my last boat, I put AF straight on top without primer, and looking at her in the yard, none has flaked off the converter - 7 or 8 years after I did it.
Other treatments require you to take the keels back to shiny metal, and in this country (especially here in the south-west) moisture soon gets back on the metal - before you can apply the treatment.

That sounds a whole lot easier than trying to get epoxy treatments on. I haven't got time to clean down to metal this year but I'll be using the rust converter on the bare spots. Next year I'll give it the full treatment as you suggested. Thanks again.
