This might do, at a better price.

Phosphoric acid ( Jenolite ) will neutralise thin rust, you need to get all the scale off.

Like wise, Fertan will also work but you have to wash it off afterwards.

Vactan will do the same job but leaves a vinyl layer.

All will accept two pack epoxy afterwards.

 

 

Really? That's the fist time I've heard that. They may "accept" two-part epoxy but it's not recommended to apply epoxy over these rust converters.

 

The only way is to remove the rust mechanically which means hard graft with an angle grinder and wire wheels/cups. To get into the corners use a welders chipping hammer. It can be done.

Could anyone tell from these pics what this is painted/ coated in ? 

 

 

My water tank was coated in a thick layer of beige epoxy cement that the builder had used. It had kept the tank in pretty good condition over 10 years but water had started to get under the coating in places and I ended up chipping the lot out with a needle gun, hammer and an angle grinder/wire wheels. I must have taken 6 buckets of the stuff out of the tank.

 

I don't know if that's what you've got?

Don't think my tank is quite that clean yet. Seems that I've got some work to do. At 6'2" and 17st, it'll not be easy!

Child labour was a wonderful thing for jobs like this.

I've enquired, they're all busy sweeping chimneys

Yes, being small has it's advantages when it comes to some aspects of living afloat and boat maintenance .

Not really - it's a horrible job. Just keep at it and you'll get there.

I cleaned mine out in 2012 - was that really more than ten years ago?

[Dibble]

You didn't used to work in the Jam butty mines by any chance? 🤣

Certainly not one of Dodd's Diddy-Men - I am 6 feet tall and was standing upright in that photograph - our water tank is integral with the bow and holds a lot of water.

I've found having a Mrs who's a lot smaller than me helps...

 

 

 

We've also got a very large integral water tank, more than 1000 litres, still access isn't too bad.

I had a 'plastic' tank put in mine years ago.  It's quite solid not one of those plastic bag affairs.  I used to black the integral tank every Spring until I found I was still getting rusty water because the inside of the feed pipe had corroded.  No regrets (yet).

Hi Lady C

 

Can I ask who fitted the plastic tank for you?

 

Thanks 

[Lady M]

The tank was fitted by my then marina.  Unfortunately I cannot tell you the tank manufacturer.
