I've got several of these to do and am planning to tackle it in the

paint with some sort of anti-rust primer, fill with polyester body
filler, sand, prime and top coat.
Is there anyone here who has renovated Crittall windows and has any
advice (other than replace them)?
...or any car body experts who can suggest primers, fillers and rust
eaters?
I thought they lasted for ever...they did on my ma's house......


They are galvanised and do last a long time but if they have
been badly painted by a cack-handed person who has damaged the
zinc coating, then rust soon gets in.
