treating rusted steel gutters

magicbastarder

i'm probably making a rod for my own back here, but i'm considering trying to restore the guttering on my house rather than replacing them.
i have what appears to be rolled steel gutters, into cast iron downpipes (house was built in 1953 i think), and the gutters seem solid albeit shoddy looking with peeling paint and rust.

if i was to take down the gutters and strip the paint and remove the rust as best i can (drill with a wire brush attachement most likely), would i be best advised just painting on red oxide paint, as seems to be standard/traditional? or would an aerosol rust-specific primer be better/easier?

i've also seen (generally american) videos on youtube of a paint on product which claims to react with and polymerise the rust, but i don't know if anything like that would be sold here.

i know there are other options which involve submerging the parts to remove rust (electrolysis and chemical), but as the sections are at least 6 foot long, that sounds like a right faff.

i also could get them sandblasted too, but have not made any attempt at pricing that.

You can do electrolysis pretty easily in a piece of wavin pipe with a piece of rebar as your cathode.
Use washing soda as electrolyte.
I have done a fair bit of it and its easy enough to do, however I don't know how much you have to do.
Soda blasting is another good option.

cheers, they're an old fashioned 6" wide, i guess getting wavin that's wider than that wouldn't be problematic?

Shouldn't be or you can use the corripipe that has the blue liner that is sealed.
