Seems to be some debate on whether or not Jags were actually galvanized.
https://www.jaguarforum.com/threads/galvanised-body-fact-or-myth.44736/

Once galvanized indicates that much of the gal has been rubbed off?
If so bare steel doesn't have much rust resistance.

It is almost 30yrs old so not surprising that there is some rust.

Those trucks were notorious for rust, finding one without significant 
rust would be near impossible.

Sounds like that is at least part of the problem.

Salt water will destroy even the very best vehicles so that really 
doesn't tell us all that much.
I've seen an early 80's Ford Bronco that was less than 2 yrs old almost 
totally destroyed by rust mostly in the chassis area, some rust on the 
body but not too bad, it was used as a beach tour vehicle and spent 
nearly its entire life on a beach, Ford replaced the chassis under warranty.

Worth a try if you have some spare time, just don't hold your breath 
expecting much of a result.
