Used SQ -400's ?

[sevenfoursharer]

Can former or present SQ pilots or GE's shed some light on the technical status of the early 747-400's (delivered 1990 - 1994) in SQ's fleet?
Corrosion, structural damages, Long storage periods at Changi?

Some of these are coming onto the market and we're interested in the work forces opinion.

Thanks in advance for the info!
