Hi
I've discovered several plubing leaks since buying my boat in March. I've now either fixed or a working on them all, but some areas of the bilge are quite rusty. After starting with a couple of other products that I was later advised against I've been putting Fertan on the remaining rusty areas that I can reach. Should I leave this as it is and put the ballast back or should it have a top coat? (Eg hammerite?)
Also the rust was quite extensive, but as far as I can see (a lot of the floor is difficult to lift up) it's concentrated in where water was pooling from the various leaks, which would make sense. I'm wondering if I should try and lift more of the floor to get a better look (which is difficult and I've already taken too much time off work), or treat the bits I can reach and hope for the best? Obviously that's not something anyone can answer for certain online, but interested to hear what other people might have done in that situation. The hull survey this Feb was very positive - 9mm at least all over - but until I read more about how rust expands I was very alarmed by the extent of it.
I'll be trying to deal with the engine bilge next (get the crud out, treat the rust, paint - what with?) so please wish me luck.
